Audio working but still exclamation mark

  Ian in Northampton 17:45 03 Jan 2013

I've just installed XP and installed all the drivers. The Realtek audio driver seemed to install fine - 'proven' by the fact that audio works - but in Device Manager, there's still yellow exclamation mark against 'other devices', 'audio device on high definition bus' and 'unknown device'. When I boot, the 'found new hardware' wizard appears. It's a minor annoyance - but I'd still appreciate any thoughts on how to fix it. My initial thought is that it may be something to do with the Intel chipset drivers not having loaded properly, but I don't want to miss with them if I don't have to.

Unashamed bump (as it was about to drop off the first page...)

Thanks guys. It's onboard sound. Woolwell: yes, I think that thread is adjacent to my problem - I suspect reinstalling the mobo/chipset drivers may be appropriate, although why they wouldn't have 'taken' in the first place, I have no idea.

Hmmm... Reinstalling the mobo/chipset drivers didn't help. I'm wondering (this being a secondhand PC) if there's some random audio device in there that I'm not aware of... Anyone have further thoughts?

It's been suggested to me that the issue is to do with HDMI audio on my Radeon 6870. I'm thinking of installing the driver here. Anyone see any problems with that? Or have any suggestions? (Other than create a restore point before doing it...) I'm running XP Pro 32-bit.

Wow - are we all anonymous now?

It's interesting that Device Manager doesn't show any working audio device - just the two devices with yellow exclamation marks.

Short of reinstalling - again - the Realtek driver, I have no way of knowing whether it's the HD version or not. The version I installed is the version recommended for my mobo, and runs as asussetup.exe. I guess I could try a different version of the Realtek driver, although that makes me slightly nervous as I have a working one.

I have no need for HDMI sound. I just want to solve this (very) minor annoyance.

I looked at the AMD site, but there's no mention of a specific audio driver for the Radeon 6870. I'd rather use an 'AMD-approved' one, but the one I mentioned is the only one I can find.

Thanks Woolwell. That's the driver I've installed... :-( The mystery deepens.

So... Further investigation found me here. I note that there is a recent release (2.70) of the Realtek driver (the one I've installed looks like it dates from 2010). I also note that there is a driver specifically called 'ATI HDMI Audio Device'. I'm intrigued, because other research I've done tells me that, if the Realtek HD audio driver were 'properly' installed, when I go to control panel/sounds and audio devices/audio, there should be an alternative default device listed. So, my quandary is, do I a) install the new driver, even though it's not strictly the one for my mobo (Realtek point out that there's a is a generic driver), b) install the ATI HDMI Audio Device driver, or c) leave well alone before I break something...?
