IDT HD Audio quit working with Vista HP64b-SP2

A couple days ago, Windows (Vista Home Premium 64) updated to SP2 and I lost sound. Now, when I boot my computer, the mute button stays orange and also the IDT control panel does not load. When I try to load it manually, it says the driver is not accessible.

I searched online quick and it sounds like I'm not the only one with this problem--though I haven't seen any fixes.
HP hasn't listed an updated driver for my particular computer yet, and last time I tried to update my audio driver, I ended up with all of these features that for some reason didn't work and made things sound worse and run slow.

It's times like these when I wonder why the heck I put up with all the inconsistencies I've had with Vista

Anyone have a potential solution? System restore is a very last resort for me.

Thanks.

 

I recently had a similar issue with our DV4t-1000 CTO, Vista SP2, and the IDT audio. See remarks at item #50 on the DV4t driver’s page here.

Unfortunately, after the update to the newest IDT driver I could not return to full functionality without doing multiple driver uninstalls and a system restore. In my case however, the system was already at SP2 so the restore was a non-event. Based on a few hours of trying nearly every combination of drivers without resolution my advice would be to:

1. Update the BIOS (if required)

2. BOOT to safe mode.

3. Uninstall
a. IDT audio drivers
b. Quick Launch & Quick Touch buttons ( windows drivers drive part of these functions while the HP drivers add the volume controls and Quick Launch for Quick Play)
c. Quick Play
d. Bluetooth

4. While still in safe mode, update the Intel Chipset drivers using the ones posted on the driver page above using the –overall function as mentioned.

5. BOOT normally, then run the registry portion of CCleaner or something similar. Re-BOOT

6. Using the older driver versions available from HP, reinstall:
a. Quick Launch
b. Quick Touch
c. Check Functionality

7. Using the older driver version available from HP:
a. Re-install IDT audio
b. Check Functionality

If all is well, then you should be able to go ahead and reinstall the HP Bluetooth and Quick Play if you use it. If that didn’t work for you, then you might want to consider backing up all your data and doing a fresh Vista Install with SP2 and sticking with the drivers listed at HP. Somehow, a number of the drivers pertaining to Quick Launch, Quick Touch, and the IDT Audio do not respond well to individual updates and seem to best be re-installed in matching sets.

You are not the first (or likely the last) to have problems with these driver combo’s. Be patient, and check for full functionality after each driver update and you should be able to get your unit back to “as advertised”. After that, be very leery of chasing updates pertaining to any of the above. In other words, “if it ain’t broke, don’t fix it”. I’ve learned my lesson on these…. and frankly I’m pretty tired of messing with them.

Last, never blindly trust any of the system drivers presented via Windows Update. Especially the ones related to "sound" on your Dv4t.

Best of luck & hope this helps....

 

Thanks for the detailed response.
I'll give this a shot some time that is convenient for me.

 

I played around for just a bit and somehow solved the problem.


I uninstalled the IDT driver and rebooted and crap-cleaned my computer. I downloaded the HP recommended driver and installed it and rebooted again. Still didn't work.

However it may be worth mentioning that the installer never told me that it was successful. It seems as if Windows took over because in my task bar, I got the bubble that says "installing drivers" or whatever as if Windows Update was doing it all. After a success prompt from that, it still didn't work. I looked and it seemed as if it installed Microsoft drivers somehow or rather it still didn't know what chip I had in it (normally under playback devices, I have HDMI, Altec Lansing, Independent Dual Headphones and SPDIF.. before IDT took over, it was just Speakers and Headphones.. plus Device Manager didn't recognize it was IDT..).

Anyways, I tried the IDT driver installer again without uninstalling (also, not overwriting the files from the previous install) and the same thing happened with the "windows update" stuff. This time however, I was excited to hear the clicking feedback when you adjust the volume.. the prompt thing came up saying it may not have installed correctly, but because it worked, I hit "this installed correctly" and whatnot.

I don't know how it ended up working... it just kind of "clicked" this time. I share my experience of course for future reference in case someone else encounters this problem. Perhaps the element is luck. Maybe it can be repeated though.

Thank you for your suggestions.

PS- I have an AMD system; and also, I would have clean-installed Vista if I had the disk.. I'm not going to buy it though with Seven right around the corner.

..so glad to have sound again

 

Sorry, I thought all the 1100 series were Intel based…. guess not. At-any-rate, good you got your audio up and it appears whether AMD or Intel the thoughts on the IDT drivers in combination with Quick Launch & Quick Touch still apply and are all sensitive to not only version but installation order.

My best luck has come with uninstalling all related items and running the registry portion of CCleaner prior to re-installing anything. Looks like CCleaner may have perhaps cleared whatever was interfering with your IDT install also. Who knows…. but it’s amazing how many people have glitches with these combo’s, how much time owners spend getiing it all to work correctly, and how often it’s related to IDT audio. Perhaps forcing the driver install as you did is the ticket. Good to hip pocket anyway.

Tunes again… thanks for the update……mission complete.
