Re: How many of you?
I'll try to explain what a did to get sound working on my presario.
OSS, It works with kernel 2.4.20 and later
#
# Sound
#
CONFIG_SOUND=y
CONFIG_SOUND_VIA82CXXX=y
CONFIG_MIDI_VIA82CXXX=y
CONFIG_SOUND_OSS=y
There is a patch from Santiago Nullo for kernel 2.4.18
I send it attached.
ALSA. I use alsa-source_0.9+0beta12-3 (Debian Woody) patching the file ac97.c
I send attached tha patch i made. It is based on the patch from Santiago Nullo for kernel 2.4.18.
Replace the file
/usr/src/modules/alsa-driver/alsa-kernel/pci/ac97/ac97_codec.c with the file
attached and compile them with:
./configure --with-cards=via82xx
make
then edit the /etc/modules.conf and add:
alias char-major-116 snd
options snd cards_limit=1
alias char-major-14 soundcore
alias snd-card-0 snd-via82xx
alias sound-slot-0 snd-card-0
alias sound-service-0-0 snd-mixer-oss
alias sound-service-0-1 snd-seq-oss
alias sound-service-0-2 snd-seq-midi
alias sound-service-0-3 snd-pcm-oss
alias sound-service-0-8 snd-seq-oss
alias sound-service-0-12 snd-pcm-oss
I suppose sound will work with later versions of alsa.
If you have problems write me and i'll try to help you.
