Hi,
I have Asus pundit with sis7012 sound device and alsa 1.0.4 under Suse 9.0.
I've got advice how to use this 6 channel device as 3 stereo channels but
there seems something not to be right (it could be my mistake).
I have /etc/asound.conf :
pcm_slave.sis {
pcm "hw:0"
channels 6
rate 48000
buffer_size 4096 # make these sizes smaller for lower latency
period_size 2048
periods 0
period_time 0
}
pcm.ch12 {
type dmix
ipc_key 47110815
slave sis
bindings.0 0
bindings.1 1
}
pcm.ch34 {
type dmix
ipc_key 47110815
slave sis
bindings.0 2
bindings.1 3
}
pcm.ch56 {
type dmix
ipc_key 47110815
slave sis
bindings.0 4
bindings.1 5
}
pcm.a {
type plug
slave.pcm ch12
}
pcm.b {
type plug
slave.pcm ch34
}
pcm.c {
type plug
slave.pcm ch56
}
pcm.dmixerALL {
type dmix
ipc_key 47110815
slave sis
bindings.0 0
bindings.1 1
bindings.2 2
bindings.3 3
bindings.4 4
bindings.5 5
}
pcm.channelALL {
type plug
slave.pcm "dmixerALL"
ttable.0.0 1
ttable.1.1 1
ttable.0.2 1
ttable.1.3 1
ttable.0.4 1
ttable.1.5 1
}
-----------------------------------------
Now I do:
- alsaplayer with mp3 file on device plug:a
- aplay -D plug:ch12 (funny is that plug:a doesn't work)
- everything is ok and mixed properly
- but if I start another alsaplayer on plug:b (probably also plug:c would be
the same), then aplay produces sound that is "interleaved" in short chunks
and also sound from alsaplayer on plug:b is also heard in addition to
original mp3 and aplay sound.
Am I doing something worng or is this somkind of bug or limitation of alsa
driver ?
Thanks in advance,
Robert.
