No sound on g51

i had g51vx Best Buy version, and i start my computer, but suddenly sound trought speakers dont works... but if i conect headphones or external speakers using the jack conector it works... any ideas??

 

you didn't change the speaker volume in the bios by chance did you? I did it to silence the boom noise when you turn on the laptop, but that actually silences the speakers totally.

 

nope dindt do that, i didn't change anything, no i onley hear whit headphones =/

 

aNY IDEAS PLx!!! WAT CAN I DOOOO

 

try resetting to user/manufacturer defaults in BIOS.

 

did that... nothing happens, only i can hear the Boom Sound at the beggining, but then.... nothing y had win 7 and linux, speakers dont work in any of these.... =/ just headphones or external speakers

 

if you turn everything to max (not BIOS post sound), can you hear something from them? static, noise, anything? or is it completely silent?

 

nothing the only sound is the boom sound at the beggining,.

 

Do you have your audio drivers installed? If you uninstalled them accidentally, they should be on the drivers disc that came with your computer.

 

there is nothing you can do, some retard at ASUS thinks these are only used at lan parties, and the users wear headphones.and they afraid you would play these in airport lobbies scaring people with explosions. I will do some testing with modifing a laptop with similar issues. I will either change the stock speakers, or get an amplified module out of a powered set. I do not think the speakers are the issue tho.

 

If you don't have speaker sound after the OS loads, you might have a broken headphone jack input, causing the jack sensor to detect an inserted plug.

I would recommend contacting the Technical Support line for further assistance.

 

hum.... i cant do that, i am from chile, i boughr this laptop at Best Buy in USA....

but maybe is the headphone jack input... but.... why can i hear the BOOM sound at the beggining whit the speakers? thats wierd....

 

Welp. Now I have the exact same symptoms as the OP. Speakers were working fine until one day, speakers stopped working but the headphone jack still works fine.

It might of coincided with a day that I used a TOSLink in the headphone jack to do a firmware update on one of my Yamaha AVR receivers over optical out. Since then, I only get sound from the headphone jack.

I made no changes in the BIOS. --- What a bummer...

Yup. Headphone jack definitely went bad. It thinks there's headphones plugged in when there isn't... *Sigh*...



Is it an "easy" fix to do by ones' self either trying to "fix" the mechanical issue or replace the headphone jack? Rather not send in the machine for repair...

Cheers,
Kermee

 

yes man i have the exact problme as you, mine hapend when i conect my computer to an lcd tv, to play PES, then when i plugged out the jack, myaudio did not work anymore.... so its broken

 

so no solution? if you find something plz tell me =/

 

I ended up RMA'ing my unit from Newegg (a US e-Tailer). So far, no issues with the headphone jack. -- The only real solution would be to physically replace the headphone jack but since it's dual analog/SPDIF, I've heard it's a pain to resolder a new one. Ended up being easier to RMA to Newegg since they paid for shipping both ways and no cost to me other than packaging tape...

Since you bought your notebook in the US and you're currently in Chile, I'd at least try contacting ASUS Global Support and see if there is anything they can do for you. -- I know... it's a real bummer

Cheers,
Kermee

 

I actually did read on here somewhere there is a registry hack that will force it to use one or the other, or both maybe... that might be a solution if you can't RMA it and don't want to dissasemble the laptop. This seems to be a somewhat common problem with these for some reason, maybe just a cheap headphone jack or bat batch of parts... not sure.

 

I'm from Chile too and I have the same problem that skinni on mi G51j.

Please help =(

 

de donde eres? de que parte?

 

The ASUS warranty is global, so if there is a service point in Chile, they will probably be able to help you. However, looking at the ASUS support page, I do NOT see a "South America" category.

Note also that ASUS service quality varies a lot throughout the world and is quite bad in some places, you may not want to go that route for a relatively small defect.

As an alternative, I would suggest investigating that registry hack solution mentioned above.

PS: Also best to stick to English.

 

i want to do that, but...how can you do this?

 

hum... i find something .... copy paste from other forum


I have the same laptop (Asus G51Vx-RX05) bought from BB in beginning of Nov. 2009.
My internal speakers worked fine yesterday and today they don't.
I checked the pins on the actual headphone jack. The problem is not software be it Windows 7, XP, or the Realtek drivers. The problem is when you slide the headphone 1/8" plug into the slot the spring pins push back to tell the laptop that the headphones are plugged in and when you slide it out the pins spring back into position to tell the laptop to use its own internal speakers.
Apparently these pins are not popping back into place and on my laptop one pin popped back out like it should and the other pin is still pushed back in as if the headphones were still plugged into the port. Don't believe me?
Turn your laptop on its side and use a bright flashlight to look at the pins. You'll see on the mic and input jack that the pins are both pushed in the middle waiting for a plug to slide into the slot. Now look at the headphone port. Notice the difference? On my laptop one pin is correctly just sitting there but the other pin in pushed out to signal the laptop that the headphones are plugged in.

I'm trying to use a small screw driver or something to fix it but its not working so far.
Next step might be to take the laptop apart myself (I've done it before to other laptops) and fix or replace the headphone jack.

Any suggestions or comments?

so... the only thing now its... try to open it, or force whit registry...

any ideas?

 

I'll admit I was pretty disheartened when I read this thread. I think this is happening to a lot of people, I'm not sure why, I've never encountered this problem before. But I will say this, I got my sound working again without sending this away.

This is the issue. The spring pin was stuck. And having dealt with Spring pin related problems in the past, I do what I always did. I shut off my lap top, spun it over, (Closed the lid first) and started prodding the hole with a saftey pin. Yea, not very professional, but you'd be amazed at what you can achieve with house hold tools.

Anyways, I blew some compressed air into the hole, (I didn't shove the nozzle in there, but just at the hole, to clean out any dust), and continued to prod the hole liberally with my safety pin. [Insert crude hole prodding joke here]. I didn't hear a click, I didn't see anything differently when I looked into the hole, but I decided to give up and restart my machine. Boom it worked.

Hope if you try this, it works for you, and you don't void the warranty by poking too hard. Like I did with my last girlfriend.

 

i will try to do the same, but not whit my girlfriend xD

 

Well damn, this is happening to me.

 

I had that happen about a year and a half ago to me, so I posted what I did that fixed it on my site at the time

It's never bothered me since.

This is a BIOS fix for the problem. It'll make the sound come out of both the speakers and the headphone jack. BEst you can do:

i will try this



edit: worked, thnx, at least we can edit every time to put headphones

 

I had my laptop speakers stop working this morning. Finally after reading this thread I went into BIOS and put the boot up sound too On(which I turned OFF before) and changed the speakers volume to 5 (where it was at 4 before). This seemed to have fixed it.

I suspect it might be the HDMI output. I watched movies last night and this morning after cleaning the fan and installing some windows updates, the speakers turned off. Could be the cleaning, could be the updates but I still suspect its the HDMI shutting off the speakers.

 

Anyone know where I can purchase a replacement audio jack/USB unit for the G51? I've seen a disassembly guide. It looks like a pretty easy fix, but Asus won't send just the replacement part. They want the entire unit, which means downtime. I develop on my laptop, so I'd really like to avoid an RMA.

Thanks in advance for any help.

 

Hi, im the owner of a G51j laptop and i have the same problem. The computer stuck on headphone mode

 

This happens to me too once in a while. Headphones work but speakers are off after booting up. I found something that works for me.

I restart - F2 into Bios - Go into advanced and turn Asus ROG Logo boot sound On (I usually have it off) - Save and Exit - Then as the Asus ROG logo shows hit F2 for Bios again - Then go back to Advanced and turn it Off again.

This seems to reset my speakers and when Windows boots up my speakers are back on again. Hope this works for you.

 

and now it has happened to me....further more...i removed the Realtek dirvers and now can not seem to install them back....it says "No SRS device found"

Sound by headphones is still working though using Windows drivers...but absolutely no sound from the built-in speakers.

I am in Pakistan nowadays and i purchased mine from bestbuy...dont know what to do....anybody has any ideas???

Edit: tried the regedit method mentioned in another post and now i have sound both from speakers and headphones. This is good for a temporary fix.

 

The reason this happens is because a computer's analog audio jack has prongs built into the walls of the jack that depress when a pair of headphones/speakers gets plugged in and pushes them.

What tends to happen with the G-series is that because they are made poorly, sometimes the prongs get stuck to the sides of the jack walls. You might have noticed that ever since the problem started, headphones and speakers have been slightly easier to plug in. This is because you no longer have to move anything out of the way.

I've tried the plug-in-and-out-again method, and it hasn't helped. I've tried going in and prying the prongs out to the side again. That didn't work either. I suggest you guys try both those before you do anything in the computer, because it's not a software problem that causes this to happen. Your drivers are not responsible for it.

 

@Kierkes
It wasn't a hardware issue for me because by turning on/off the startup logo sound in the bios fixed the issue for me. Speakers work

 

Before messing with the hardware make sure that the hardware is actually the problem. You can try booting some Linux Live CD, such as Ubuntu, and see if you have sound there.

If you figured that the hardware is the actual problem, then you could carefully open the laptop and see what exactly is getting stuck in the 3.5mm plug. There are 3 contacts there. 1st is the common wire, which is the metal right. The other two contacts are "bendable" metal plates. The way I always fix loose 3.5mm plugs is just by slightly bending them inward, toward their original positions or even slightly more. BUT be careful not to break them and make sure you don't bend them too much to the point that they short when nothing is plugged in.

 

Perhaps. All other things I've looked up have indicated that.

Too ambitious for me, haha. I've got another potential fix brewing (that works for someone with my setup, at least) A great way to test those plates is, as I said, to plug something into that jack, and into another jack, and see if the headphone jack is easier to push it into. If it is, hardware problems.

 

Many people have a same problem. That's a hardware problem.

 

Had the same problem.

How it happened:
• I had a pair of headphones plugged in,
• changed some random sound recording settings,
• pulled the headphones jack out,
• my speakers weren't working.

What I did next:
• came here, read some messages,
• put a flashlight in the headphones port, put the light in the other ports, observed a huge difference,
• put a jack in every port, also observed a huge difference in the ease of handling,
• proceeded to finish reading the thread.

How I resolved it:
• enabled the post sound,
• my speakers work again.

Summary: yes, the headphones port is much more used than the others, but the problem came from that BIOS option. Funnily, I have restarted my laptop several times since I modified the option a few days ago.

Fun fact: I omitted to write that somewhere on the way I reinstalled the sound drivers, although I was pretty sure they had nothing to do with the problem, but I had just deleted some not-sure-they-are-not-critical files just before it happened. Bonus: got rid of Realtek HD Audio Manager, which I don't use (yet).

My conclusion: it's not a hardware problem, but BIOS. Besides this tale, there is a premise I find pretty plausible: the hardware system does not detect when the pins are pushed aside, but when the pins get connected; how they get connected: when headphones are plugged in, a circuit is closed through them and there is a detectable voltage drop through them. I find this solution to detect if something is plugged in more convenient than the other.

But maybe I'm saying the same thing, but missing the fact that when the pins remain pushed aside, they short-circuit with some elements that are there in the laptop; which would be VERY BAD, meaning this also happens whenever someone who has a healthy G51 plugs a jack in the port. Hopefully I am not saying the same thing.

I'm no good at electronics, but my opinion is, seeing that a jack has three contacts (separated by two isolating cylinders of which only the top rings can be seen), that there are two pins for two channels (stereo) and one for closing the circuit.

If someone with a healthy G51 and some broken headphones could test this premise by cutting the cables from the speakers (and carefully separating them, thus opening the circuit)?

 

i did what you say... whit the bios... but nothing happen.... =/ to bad for mee i'm looking for other solutions

 

Found this datasheet on the plug.

http://www.singatron.com/eng_pdf/2SJ-A373-001.pdf

Seems some of the posts people have put on here don't make much sense. This particular jack is not the same as the line in and mic jacks, they are made my different manufacturers and therefore will not look the same when you shine your flashlight into it.

looking at the schematic seems pin 6 is common, pin 1 is right speaker and pin 4 is left speaker, pin 5 is ground or case, pin 7 is the connector to tell if it is plugged in (maybe?)

I checked continuity across my pins with the following results
Unplugged headphone
pin 5 to outer metal jacket connected
pin 6 to pin 7 not connected
pin 5 to 6 not connected

Plugged in
pin 5 to 6 connected
pin 6 to 7 connected


Seems like the audio jack is working properly I am not sure what the IC is actually doing cause I dont see any LEDs lighting up.
still no sound from internal speakers and headphones work fine.

 

thanks rezigrene..it worked like a charm..now i don't have to send it back.lol

 

Im not sure if this is an Acer drivers issue or merely my unfamiliarity with Win7, but heres my issue:
Recently, the external speakers on my laptop havent been working, recently as the last week or so. If I connect some headphones or my TV through an HDMI cable, the sound works fine and also when I start up the computer, I get the splash sound before it gets into Windows. Ive gone through all the normal settings, mute (obvs), the sound settings in the Control Panel, etc and they all seem to be set properly. When I play some sounds I can see the volume bar project the sound levels, but nothing is coming out of the speakers.
I think it may be related to hooking the TV up to the laptop through the HDMI. It was working last weekend fine, but after hooking the TV up to the HDMI in the laptop on Sunday it has been wonky. Is there some place that I can disable the HDMI sound out on the laptop? In the sound properties, I can set the default output to the speakers vs the HDMI, but that doesnt work.
I hope this description isnt too obtuse. Im at work now trying to remember what I did. Its probably something stupid and I hope its an easy answer like: "Go to Control Panel and hit XXXX, you dumbell"

Hmmz. Looks like I have the same issue. I posted this morning about my speakers not working. I noticed in teh past when I plug my headphones in it detects them with a notice dialog. Since the speakers stopped working, I havent seen that popup. Ill investigate tonight

(this is not a bookmark )

How long is the warranty on this laptop? I bought it from NewEgg probably 12-14 months ago

 

It depends, some people get 1 year, some get 2. There is no physical difference between the models, it all depends on the suffix of the laptop model number.

 

flip it over and read the Asus label

 

hum... this si weird... because i`m still thinking that is a hardware problem... i installed many Different OS, and get only sound trought the headphones, and now.. I installed ubuntu 11... and NO SOUND... so i cheked this link, and now i can hear whit my headphones...

[ubuntu] No sound on Asus G51VX - Ubuntu Forums

weird... maybe the problem is in the bios...

 

It Is a hardware problem I fixed it through disassembling my laptop many times and experimentation with the USB + audio board that fails.

I will explain here once and for all the problem and how to fix it

Bottom line the laptop is a piece of s#it poorly built AND designed by ASUS mostly in China for pennies on the dollar.

Owning this laptop has led me to loose my faith in the company and I probably wont buy another one.

Anyways onto the problem.

Yes the jack is faulty Among other things* (explained later)
Yes sometimes you can fix it . NOT ALWAYS.
If you cant fix it you wont have sound from either speaker or headphone while using the Realtek driver.

The reason sound can work on other Operating systems is because it's not being locked like it is with Realtek. (locked in 1 mode or the other)
meaning you can still hear the speakers.

The only way to fix the problem ONCE AND FOR ALL. is to replace the whole board or do this modification I will explain.

Take ALL the screws out of the bottom of the laptop
Their are 3 styles of screws in the laptop.
long regular, short regular and Keyboard screws marked with a K.

grab a Phillips head screwdriver and get to work

once they are all out. flip the laptop over. remove the keyboard by carefully hitting the 5 lock wings ALONG THE TOP with a needle or something to release the keyboard.

Remove the 2 screws under the keyboard.

Then take a guitar pick or a credit card and pry the rubber handrest from the bottom housing.

Now you can see the faulty board.
Remove the 1 phillips screw holding it and pull the cable from it carefully.

Now you need to remove this micro controller that tells the computer if headphones are plugged into any of the jacks

Take a pair of needle nose pliers GRAB it hard and TWIST. make sure you dont hit any of the other resistors or things around it. We dont want to hurt anything else just the micro processor in this image.



remove only that and put everything back together. you will have sound from the speakers again.

NOW onto the solution of using headphones again.
Buy a USB adapter from any online store such as this one.
Amazon.com: Syba SD-CM-UAUD USB Stereo Audio Adapter, C-Media Chipset, RoHS: Electronics

Then you can plug in all your device you want happily ever after and not worry about those piece of garbage ASUS ones

* OTHER KNOWN PROBLEMS G51 LAPTOP

Keyboard keys not working.
Overheating
Sound skipping and making odd noises when listening to audio
Audio jacks fail.

The keyboard can't be fixed in most cases I had to replace mine. It's because of the bad design the ribbon cable is under constant pressure when you type and it cracks it in half thus resulting in a short connection.



The overheating can also be fixed but it's a hassle and their are already threads on this forum about it.

Overall I would say that this laptop is not dependable. I would give it a 10% reliability scale VS my IBM t61 business laptop being a 96%

Hope you found this useful so you dont have to trash the G51

 

I am going to agree with freedom..ty laptop combined with ty nvidia oven card. I will have to save up double the money and purchase a mac book pro..but hey, I will have that thing 5 years from now. I would only have to replace it because, i want new stuff not because its broken.
