View Full Version : [ubuntu] No alsa sound on ASUS M4N78 Pro Motherboard with Lucid

June 2nd, 2010, 06:09 AM
I just did a clean install of 32 bit-Lucid on a DIY box with this mother board and AMD AthlonII X4 CPU. The MB has an NVIDIA IGP GeForce 8300. I have installed the current Nvidia driver and removed the pulseaudio. The system is up-to-date with apt-get update. I have tried playing videos and mp3 files and there is no sound.I would appreciate if someone can help me get the alsa sound working. I am posting what I thought was the relevant information for the experts to figure out:

Yes, I have unmuted and maxed out the volumes in the alsamixer.

install paprefs and gnome-alsamixer and set your prefs with it (app sound gnome-alsamixer)

I installed gnome-alsamixer and checked the settings. Everything was already unmuted the master was max. I set everything max except mics.

I have not installed paprefs because it seems it is for the pulseaudio. When I read around, many people with alsa problems resolved their problems after removing pulseaudio. So, I removed pulseaudio. Not that I know much about either. I am just trying to make the sound work properly.

BTW,When I tried System>Perferences>Sound, I got only
"waiting for sound system to respond" msg on a small window and nothing else.

Do I need to add something at the bottom of alsa-base?
Do I need to add some settings in a file in /etc/modprobe.d/xxx?
How do I know if via chip or something setting is correct for the mobo in alsa?

I know this mobo is a challenging to get the sound right. Unfortunately this is what I've got. Can someone please help me.

Well, using the alsa upgrade script from this form, I have installed the current alsa driver. It went successfully and I heard the drum beat for the first time at the first boot which was encouraging. However, it no sound and no more drum beat later. When I ran alsaconf, no card was found. But when I ran alsamixer, all speakers/ports were there. I unmuted and maxed out the volumes. Still no sound.

I think the solution is near, someone reading this please help me.
