Open Sound System on Debian

Postby markhobley » Sat Sep 03, 2011 8:23 am

Has anyone managed to get the open sound system working on Debian? I have installed the Debian precompiled package oss4-base. When I run osstest, I don't get any sound, but I am getting an error message which reads "PÃ¿ì· (audio engine 25700)". What modules should be loaded, and which alsa modules should be blacklisted on my system?

lsmod currently reports:

tun 17827 0
snd_via82xx 22676 0
snd_ac97_codec 84243 1 snd_via82xx
ac97_bus 12462 1 snd_ac97_codec
snd_pcm_oss 36394 0
snd_mixer_oss 17713 1 snd_pcm_oss
snd_pcm 53284 3 snd_via82xx,snd_ac97_codec,snd_pcm_oss
snd_page_alloc 12899 2 snd_via82xx,snd_pcm
snd_mpu401_uart 13421 1 snd_via82xx
snd_seq_midi 12744 0
snd_rawmidi 18695 2 snd_mpu401_uart,snd_seq_midi
snd_seq_midi_event 13246 1 snd_seq_midi
snd_seq 39752 2 snd_seq_midi,snd_seq_midi_event
snd_timer 22196 2 snd_pcm,snd_seq
snd_seq_device 12985 3 snd_seq_midi,snd_rawmidi,snd_seq
snd 38777 10 snd_via82xx,snd_ac97_codec,snd_pcm_oss,snd_mixer_oss,snd_pcm,snd_mpu401_uart,snd_rawmidi,snd_seq,snd_timer,snd_seq_device
soundcore 12992 1 snd
via_rhine 22501 0
i2c_core 19141 5 radeon,i2c_viapro,drm_kms_helper,drm,i2c_algo_bit

Presuably some of these are alsa, and some are oss. I would like to blacklist the alsa ones and use the oss ones. Can anyone help?

Per the lsmod list, oss isn't loaded, only ALSA (and unrelated) modules are listed. All the ALSA modules are the ones starting with 'snd'.

Unload ALSA (stop all mixer and other ALSA-using programs then run something like "lsmod | awk ' { print $1 } ' | grep snd | sudo xargs rmmod") and try to start up oss ("sudo /usr/sbin/soundon"). Afterwards, try osstest again.

(Oh, and I'm running OSS on debian/unstable, but I'm not using the distro package)
