alsa.. multiple sound streams - hijinks - 2005-06-21
I know slackware doesn't default to any alsa rc file. Its possible to use the PCM layer of alsa to have more then 1 sound stream doing at the same time. By default all alsa enabled alsa apps look for a file in your home dir called .asoundrc
So just use my contents .. results may vary
Code:
pcm.ossmix {
type dmix
ipc_key 1021 # must be unique!
slave {
pcm "hw:0,0"
period_time 0
period_size 1024 # must be power of 2
buffer_size 8192 # dito. It
#format "S32_LE"
#periods 128 # dito.
rate 48000
}
# bindings are cool. This says, that only the first
# two channels are to be used by dmix, which is enough for
# (most) oss apps and also lets multichannel chios work
# much faster:
bindings {
0 0 # from 0 => to 0
1 1 # from 1 => to 1
}
}
# Redirect to ossmix
pcm.!default {
type plug
slave.pcm "ossmix" # use our new PCM here
}
# Redirect to ossmix
pcm.dsp0 {
type plug
slave.pcm "ossmix" # use our new PCM here
}
# mixer0 like above
ctl.mixer0 {
type hw
card 0
}
