Audio on ASUS M4N78 PRO motherboard

If anyone has successfully installed the alsa driver on the board, please post which distro you are using especially if it is either Debian or Ubuntu.

I have wasted so much time on this issue and still no joy.

Thank you.

Could you please post the output of lspci -v ? Let's see what audio chipset your mobo uses.

Maybe you have the same problem as I had a year ago with this type of motherboard. Also couldnt find the mixer / sound card until I changed the following settings in the BIOS:

Code:

Bios Setup >> Chipset >> South Bridge Chipset Configuration >> 
               AZALIA AUDIO              [Internal Codec + External Codec]
               Front Panel Select        [AC97]
               SPDIF Mode Setting        [SPDIF Output]

I just successfully got the audio working on my Asus M4A785TD-M EVO motherboard after a substantial amount of effort. I run Debian 2.6.26-2-amd64. To the best of my knowledge, the problem appears to be an old version of the alsa module that comes with the distro that doesn't support the audio card/chipset on this mobo. Here are the steps I used with the caveat that of course these may be unique to some extent to this setup. You might need to run the following as root using sudo or su. I'm assuming you have gcc and the kernel sources installed correctly.

1. Make sure you have the packages installed...

aptitude install alsa-base

2. Download alsa-driver-1.0.23 from http://www.alsa-project.org/main/index.php/Main_Page into whatever directory you're working in.

tar jxvf alsa-driver-1.0.23.tar.bz2

cd alsa-driver-1.0.23

./configure

make

make install

3. Run alsaconf.

4. Run alsamixer and unmute the master channel!

That's it! If that doesn't get the thing playing, you could try passing specific arguments to the module using:

modprobe snd_hda_intel model=6stack

But I'm not sure this last step is necessary so long as you compiled and installed the 1.0.23 module successfully.

I will update if I have any more insights - I'd be interested in hearing the experience of others with this frustrating problem.
