Hi--
I was looking over the config data I just sent,
and I'd love some explanations.
(1) what do soundcore and snd do?
I assume one provides the ALSA api, but what about the other?
(2) why do some apps grab a control channel and others not?
(2A) what's a control channel control, anyway?
Example:
I have fuser(1) output that includes:
USER PID ACCESS COMMAND
/dev/snd/controlC0 jones 4690 f.... gkrellm
jones 20115 f.... firefox-bin
/dev/snd/pcmC0D0p music 4368 f...m esd
music 4373 f...m esd
jones 17717 ....m firefox-bin
now, gkrellm adjusts volume, so I assume that's one thing you need
a control channel for (unless you are going to drop the volume within
the pcm stream).
why doesn't esd have a control channel?
do control channels just control out of band info like volume?
do control channels have anything to do with
what encoding/sample rate the chipset expects?
do control channels control hw mixing?
--thanks more
