Hello,
I try to make my 5.1 speaker set work properly on an SB Live! Player
with Alsa from kernel 2.6.17. Most things work well, but there is
something that feels like a bug or inconsistency in user interface:
The volume for rear speakers, center, bass speakers seem to behave
indepently from any other controls. When I adjust "Master" setting, it
does not act like master. It is only applied on the front speaker pair,
all others are not changed. I need to go to the particular control
setting in alsamixer and tune them independently. Every time.
That does not make sence. I expect Master to behave like Master, a
factor which is applied to all available speaker volumes and playing
input sources.
Further, the PCM control setting is also only applied to the rear
speakers. And I do not see how to copy the analog stereo input from
CDROM to the rear speakers. Currently I use the following .asoundrc to
achieve that with PCM:
pcm.!default {
type plug
slave.pcm "surround51"
slave.channels 6
route_policy duplicate
}
Does anyone a good idea how to make mixer behave "normally"? Currently,
it really sucks. I cannot tune the volume of all speakers at once, I
need to change front, rear, center explicitely.
Eduard.
