Need help troubleshooting ALSA in Debian please!
Hey guys, I've installed a minimal Debian system from netinstall, then installed gnome-core.
I have installed alsa-base, alsa-mixer and other alsa tools, but cannot get any sound. Trying to change volume gives me a "no device detected" or similar.
Trying to run alsamixer gives me "cannot open mixer: No such file or directory" both as user and root
My user is already added to 'audio' group
Speakers are all plugged in/turned up
Somehow, I don't think it is detecting my audio device
Output of lspci (in regards to audio) is as follows
00:1b.0 Audio device: Intel Corporation Device 1e20 (rev 04)

Any help is greatly appreciated
What does '/sbin/lsmod | grep snd' show?
Since you have done a minimal install, I would guess you have not installed alsa, and the sound drivers. I think the driver snd-hda-intel.ko would be the correct driver. You will also need soundcore and snd loaded.
Try a 'locate snd-hda-intel.ko' to see if you have the driver. If not, you will have to find it in the deb packages and install it. That is a common driver, so it should be in a .deb package. I believe sound and snd are also needed.
'locate: can not stat () `/var/lib/mlocate/mlocate.db': No such file or directory'
I can't find snd-hda-intel.ko for my kernel. I'm using Squeeze with 2.6.32-5-amd64
That driver should be in the repos. Look there first. I don't run debain, so I can not tell you what the package will be called.
Unfortunately, the snd-hda-intel.ko package is not in the repos. In all fairness, I don't even know what I'm looking for.
Any other ideas?
Ah, here's an update...
I used 'sudo updatedb'
Then I used 'locate snd-hda-intel.ko' which returned '/lib/modules/2.6.32-5-amd64/kernel/sound/pci/hda/snd-hda-intel.ko'
So it appears I have this file. What next?
As root, three commands should load it.
1. 'modprobe soundcore'
2. 'modprobe snd'
3. 'modprobe snd-hda-intel'
All commands without the quotes, just what is between them. You should get no feedback. In this case, no news is good news. If everything loads, then bring up a mixer, make sure nothing is muted, turn up the sound and see if it works.
If anything fails, copy and paste the errors.
as root. I received no error messages.
Running alsamixer returns 'cannot open mixer: No such file or directory'
It appears you do not have alsamixer installed. Install it, or any other mixer will do.
I would guess alsamixer is part of asla-utils. You should have sound now.
