Windows 7: No Audio Device Detected


31 May 2012   #1

Windows 8.1 Pro x64
 
 
No Audio Device Detected

I have an old HP Pavilion dv9608nr and recently from time to time my Conexant audio device isn't detected by Windows & It doesn't even appear in Device Manager.

Things I've tried:
Scanning for hardware changes - No change
Trying to reinstalling the driver - No device detected
Using a Linux Distro Live CD - Works perfectly
Restarting the Audio Service - No change
SFC Scan - No change.
System Restore - No change

I'm out of ideas. Any suggestions other than reinstalling Windows?

It sounds like either failing hardware or an incompatible driver. After looking at the HP support site I can see that there are vista drivers for this model but nothing for 7. It may be time for an upgrade...

I had an HP recently where the USB ports were intermittently malfunctioning and then completely failed altogether. Turned out to be a failing motherboard, seems to me that your hardware is most likely failing

Yep, HP doesn't offer any Drivers for Windows 7 but those which were previously installed were from Windows Update and were released in 2011. I've been having that bad feeling that the hardware could indeed be failing, seems that a reinstall/repair install might be my last option here.

I'm inclined to lean toward a hardware failure because you've said that the device even disappears from device manager when it isn't working. Normally when hardware isn't working it will still show up, but with a warning indicator on its icon.

Yeah, this makes sense, I guess this case is solved. Thanks for your input.

No problem, it's unfortunate that the hardware is at fault here. Hopefully you have another machine to fall back on
