Public bug reported:
Binary package hint: pulseaudio
Hello,
I have createive 5.1 on ubuntu 9.10 Karmic Koala. After pure formatting the
drive I've installed it. I have these serious problem:
1. my center speaker is somehow switched with rear left - and I am not able to
switch it correctly (except changing wires:)) - I see no gui or config (except
daemon.conf value default-channel-map - which takes no effect for pulseaudio
-k; pulseaudio -vvvv)
2. my right repro (rear and front) stutter, they switch on and off maybe 2
times a second (I have tried to set default-fragment-size-msec to 24, but
nothing)
3. I see no gui for contolling volume of sound (each speaker individually) -
in sound preferences - output: I see some ballance (left/right - nice), fade -
what is this? and subwoofer (when I move with subwoofer - whole output volume
is changing and vice versa; except that moving subwoofer behind the center
value makes my mp3 sounds like a tin or metal plate); also Subwoofer value is
influenced by my mouse media key for controlling sound - it should control only
output volume not subwoofer with it
I have these values in system:
home .asoundrc
pcm.ch51dup {
type route
slave.pcm surround51
slave.channels 6
ttable.0.0 1
ttable.1.1 1

ttable.0.5 0.5
ttable.1.5 0.5
}
