I hate to start another thread on ALSA and particularly VIA VT8233 because there's the http://www.gentoo.org/doc/en/alsa-guide.xml written with this soundcard as an example, but I can't get this working and need help.

I've got a no-name motherboard using the VIA chipset with built in sound and I can't get sound to work. I don't think it is hardware. When the system reboots it beeps via the soundcard/speakers. Plus, it worked when I briefly tried Ubuntu.

In KDE, in Control Center, when I test sound, I get a slight spike in CPU usage as if it should be working. Putting a CD in doesn't give any errors, but no sound. Using aplay doesn't work either.

My userid is a member of the audio group.

Code:

# amixer
Simple mixer control 'Master',0
  Capabilities: pvolume pswitch pswitch-joined
  Playback channels: Front Left - Front Right
  Limits: Playback 0 - 31
  Front Left: Playback 24 [77%] [on]
  Front Right: Playback 24 [77%] [on]   


Code:

# lspci |grep -i audio
0000:00:11.5 Multimedia audio controller: VIA Technologies, Inc. VT8233/A/8235/8237 AC97 Audio Controller (rev 30)


I have kernel 2.6.9 with sound as modules. I've also tried when compiled in to the kernel. Didn't help.

Code:

# cat .config
CONFIG_SND=m
CONFIG_SND_TIMER=m
CONFIG_SND_PCM=m
CONFIG_SND_RAWMIDI=m
CONFIG_SND_MPU401_UART=m
CONFIG_SND_AC97_CODEC=m
CONFIG_SND_VIA82XX=m



Here's a partial listing of lsmod :
Code:

# emerge alsa-lib alsa-utils alsa-driver

# cat /etc/devfsd.conf

# ALSA/OSS stuff

# the audio devices
LOOKUP          snd          MODLOAD ACTION snd

One of the many things that I'm not sure about is that I installed ALSA last (after KDE, Gnome, etc) and when I emerged the system I didn't have any USE flags that referenced ALSA.

Seems like it must be something obvious to everyone but me. What more should I be checking?

Thanks for reading, and of course if more information is needed I'd be happy to post it.

alsa-driver is not needed, but i think it's not the case. Maybe try emerge xmms with USE="alsa" and give it a try (using alsa output plugin). aplay didn't work well on my VT8233.
