I am using alsa with asterisk. The asound.conf is below. When I start asterisk with /etc/asound.conf present I get errors on the console that: chan_alsa.c:304 alsa_card_init: snd_pcm_open failed: Invalid argument If I remove the asound.conf asterisk starts up and works. However I NEED the asound.conf for another application. What might be the issue here? THanks jerry /etc/asound.conf ------------- # This is /etc/asound.conf # # this makes legacy OSS apps use alsa software mixing dmix pcm.dsp0 { type plug slave.pcm "dmix" } # mixer0 can stay unchanged, because it isn't used anyway, I guess ? ;) ctl.mixer0 { type hw card 0 } # this makes native ALSA apps default to using dmix pcm.!default { type plug slave.pcm "dmix" } -----------
