Noise from Headphone Jack NP9262

Hello there. Finally got my NP9262. Been busy setting it up and installing and getting it to the way I like it.

I've been able to get things mostly going from what I learned from this forum and elsewhere. Seems to be going all ok. However, one thing.

Noise.

Not noise from the fan or a popping or crackling...well maybe crackling?

When I used headphones with my old Inspiron, there was no or very little noise on the headphones. What I mean is that little static background white noise. Just a quiet hum. I hope you all know what I mean.

Anyway, I updated drivers, got the newest from Realtek. I thought maybe bad power but I unplugged it and ran it off battery but still the same noise persisted.

I messed around with the audio options and I found that if I chose mute all, it reduced the noise but did not eliminate it.

I tried searching and scouring and went through pages of thread but no help regarding this issue. I can't be the only one right? Thanks for all the help.

 

Interesting that it happens even when muted. Defintely sounds like some sort of interference. Does it still happen if you unplug the AC adapter? You might consider giving Sager a quick call. They are pretty easy to work with.

 

Try muting the onboard laptop mic. Sometimes when it is enabled and you move your hand over the mic area it will create a static noise.

 

Tried unplugging it. I ran off the battery. Still the same deal.

Also tried muting the mic.

Tried muting various other options in the RealTek manager thing. Like Front, Center, Subwoofer, Rear, Digital Out

I tried almost every combination I could think of to no avail.

Are you guys that are reading this thread with a 9262, none of you have this noise that I have when you use headphones or earphones? I know it's not the quality of my headphones cause they worked perfectly fine before.

Thanks.

 

Eh, you haven't tried a different set of headphones yet?

 

Changed drivers from Realtek?

PS: Do you have SRS WOW?If so can you share the drivers?

 

Have you tried a ground loop suppressor, such as the EbTech HumX?

 

For it to be a ground loop it has to be plugged into a grounded outlet. Since it has the same problem running on battery power alone, I'd have to think it's something else. As already asked, have you tried other headphones, external speakers, stereo system, etc., etc.? Do you hear it from the internal speakers or only your headphones? Since it happens with everything muted, I'd suspect some sort of interference from something else on the laptop.

To determine if it's purely hardware, rather than being in some way related to drivers, try going into your BIOS when the computer first comes on. Just let it sit there and then plug in your headphones to listen for the noise. If it's crackling and breaking up at a screen where there is no audio at all and no drivers for audio either, that would tend to suggest it's an issue with the headphones or the laptop sound hardware.

 

I've never used headphones with mine, will give em a try once I get home from work though.

 

By changed drivers, I meant I downloaded the latest drivers from RealTek. I don't think they have SRS WOW. I don't see anything in the Realtek manager about that or the logo anywhere.

I tried using various other headphones/earphones. I still get that background noise/hum.

Are my ears just really sensitive or something? NO ONE has this problem?

 

Strange as it might seem, that could be it. It might be a very high frequency sound and you just have very good hearing. I spoke to a customer once who returned her laptop because the sound of the AC adapter rectifier was driving her crazy. No one else in her home or any of us on the phone could hear a thing.

 

AFAIK, the srs wow is hardware based. Just try playing some music, then press fn+2 (thats 2 NOT f2) and see if it makes a difference

 

Aw fooey, I have been tied up...or I guess you can say tubed up with the new water cooling system that I am installing in my desktop for the last couple days. I will try some headphones out on mine once off work. At least I really hope I will remember to. My desktop has finally started its 24 hour leak test after stopping a couple leaks that were discovered on its initial start.

 

Well I just tried some headphones with 9262 for the first time and I must say, I didn't notice anything out of the ordinary. Sounds pretty normal to me. Sorry I could not help more. Of course I think my hearing is not nearly as good the average person. Too often have I jumped out a airplane or fired a weapon without hearing protection.

The headphones I used were some little Sony earbuds, the kind with the squishy rubber cup that goes in your ear and pretty much blocks out all other sound around you. I use em when taking a long trip on the motorcycle.

 

I don't get any noise from the headphone jack, nor my USB headset. Your hearing must be much more sensitive than the rest of us.

 

Maybe it is just me...what's strange is that the noise isn't there all the time. Or at least not as loud. When there's a disc in the optical drive and it's being read, the noise kind of dies down a bit, not completely though.

It's really strange. I know there's always some level of background noise in speakers and headphones. Much like if you just turn up your speakers all the way up, you hear that kind of static/buzz/hiss sound.

I guess I'm going to have to just live with it or something.

 

Don't know much about electronics, but it sounds like you've got a circuit that's not grounded properly. How carefully did you inspect the connections on the motherboard when you opened it up?

If you want to see the wiring schematics, you can get the service manual for the D901C from the Eurocom website under the products library.

 

Well I have the same problem with my NP5793. Compared to my old Inspiron 9400, the NP5793 outputs horrible amounts of background hiss / static sound.

I believe this might be a "trait" that comes with all Clevo laptops, probably because of the cheap components that Clevo uses in their computers.

 

To my knowledge the Clevo D901C/NP9262 does have the same GJOD issue as the M570RU & M570TU

 

Since there isn't a PCMCIA slot for the 9262 (unless I missed it), what's a good solution around using the jack if I get it and don't feel like opening up the case for a bad connection etc? I have a good duo of 80 watt speakers by Phillips ( http://sector29.com/PRODUCT_PAGES/263/263-PHLMMS321.html ), and it sounded great on my 5670, but could a sound card be a good addition to the 9262? Even if so, is there anywhere to put/attach it?

 

^ use an express card

but realize that it, too, has some issues:

Thanks dit_xi, but that doesn't seem to apply to me since these speakers I have are 2.0. If there is no horrible/crackly background notice on my audio jack, would there be any point, as in is the sound more full/richer/etc?

 

I didn't open up the computer at all. Well, I did briefly to install another hard drive. Other than that, I didn't inspect the motherboard or anything at all.

Is there a possible fix for this? I'm all for opening it up and messing around with it to improve this a bit.

I mean, I guess it isn't THAT bad....but much like a mosquito bite, it would just be a whole lot better if it just wasn't there.

Also, I'm glad to read that I'm no the only one to experience this background noise/hiss. Just puts my mind at ease that I'm not nuts.

 

hello!! i realise that i've the same problem as you! there seem to be somesort of distortion coming from my external speakers, such that when a song ends and the next song starts, there is a 'shhhhhh' inbetween the songs.. kinda irritating, and loud too.. on the laptop's speakers there's no such problem, but happens on externals.. is this the same problem as yours?
