I'm having problems emerging alsa-driver for my via8233 sound card.Set the ALSA_CARDS environment variable to "via82xx", then emerge alsa-driver.
I run kernel 2.4.20 I followed instructions on http://www.gentoo.org/doc/en/alsa-guide.xml - makeconfig - recompile
During 'configure' emerge replies with:
checking for which soundcards to compile driver for... Unknown soundcard
via8233, exiting!
I tried emerging with alsa-driver 0.9.8 and 1.0.0-rc2The driver you need is 'via82xx' as above.
Can't find anything in the forums. At most I got some information that in some packages 8233 was not included.
lspci returns: 00:11.5 Multimedia audio controller: VIA Technologies, Inc. VT8233/A/8235 AC97 Audio Controller (rev 60)
Does it mean that I can use 8233, 8233A and 8235 drivers?
If not, which one is the one?
I had a couple of symptoms when playing MP3s using this card with ALSA:
1) If using an app that goes through ALSA's OSS emulation, then after 19 seconds there would always be a severe distortion for second or two.
2) If using ALSA direct there was a fair amount of static noise. A bit like listening to a dusty vinyl record.
These were sorted out by adding the following line to /etc/modules.d/alsa
options snd-via82xx dxs_support=2
You can get more info on this by checking out the alsa-user and alsa-devel mailing lists. See www.alsa.org for info on these lists.
