Audio not working (Realtek ALC861VD)

[Commodore Guff]

Okay, so I just installed Feisty (x64, x86_64, amd64, whichever you prefer) on this system. The problem is that there's no audio.
It seemed to detect it fine at first, but there was no output. So I did a little looking around, and followed this guide.
It didn't work. In fact, now it thinks I have no audio device at all.

Can anyone help?

Can you open a terminal and type 'sudo lshw -class sound' and post the output from that here.
Can you also type in a terminal 'cat /proc/asound/card0/codec\#*' and post the output from that here.
(that command ends with the hash and star symbols in case its not clearly visible on your monitor)

lshw:

Oh, and just to rule out my own stupidity, yes, the speakers are connected, and the sound works in Windows.

Anyone?

As far as I see there is no alsa support for your card - but oss seems to work!

So, what can I do?

[Commodore Guff]

I'm sorry if I seem impatient, but I'd really like to have sound.
If OSS supports my audio, well, what can I do now? I'm still somewhat of a newbie here.

Who could tell?
A good start would be to check how to revert the changes you made by following the guide you mentioned earlier.

May be you could give the forum some more hints.
lsmod | grep snd

to see which sound modules are (auto)loaded.
Check if the module for your soundcard is loaded.
For example my onboard soundcard from nvidia uses snd_intel8x0,snd_ac97_codec (amongst others)
ls /proc/asound/
to see if any soundcards are present

Did you try a live distro like Knoppix - Mr Knopper puts a lot of modules on his Live DVD's - and usually if it works with Knoppix you are sure your hardware is supported - then you know if it makes sense to put some effort in getting your desired distro to work with your hardware.

Also important to send a service request to mobo retailer, manufacturer just to make sure that you care about their hardware being supported by all OS!

I have since reinstalled Ubuntu.
Also, I'm just going with plain 32-bit x86, now, rather than x86-64. Same problem, though.

Is there something more that I'm supposed to do with that? Sorry.

I might give it a shot, though I can't guarantee that my DVD burner would not explode during the process.

Thanks.

lsmod output seems quite sane -you have a supported High Definition Audio soundcard therefore snd_hda_intel, ALSA add-on OSS/Free emulation modules are loaded as well, now for your own benefit you can read
less /proc/asound/cards
less /proc/asound/devices
or post it here

You could also try System-Preferences-Audio to choose and test the output device
You could post by which means you tried to get sound response - i.e which program with which audio settings.
