Hello,
thanks for the module-remap-sink - this is apparently excatly what I need
to have virtual soundcards for my dual-seat setup.
However, I am probably doing something wrong, because even when
I move the stream to another virtual sink, almost all outputs still play.
The detailed description follows:
My OS is Fedora 10/x86_64 (pulseaudio-0.9.13-6.fc10.x86_64).
My hardware is ASUS M3A32-MVP mainboard. The sound device is reported
by lspci as "ATI Technologies Inc SBx00 Azalia", alsamixer -D hw:0 reports
"Card: HDA ATI SB", and "Chip: Analog Devices AD1988B". This card has six
rear jacks, described in manual as
Line in
Line out (front speakers or headphones)
Microphone
Center/Subwoofer
Rear speakers
Side speakers
I have tried to disable module-hal-detect and module-detect
in /etc/pulse/default.pa, and instead added the following physical
device, and four virtual devices:
load-module module-alsa-sink sink_name=eightchannel device=hw:0 channels=8 channel_map=front-left,front-right,rear-left,rear-right,center,subwoofer,side-left,side-right
load-module module-remap-sink sink_name=virtfront master=eightchannel channels=2 master_channel_map=front-left,front-right channel_map=front-left,front-right
load-module module-remap-sink sink_name=virtrear master=eightchannel channels=2 master_channel_map=rear-left,rear-right channel_map=front-left,front-right
load-module module-remap-sink sink_name=virtcentersub master=eightchannel channels=2 master_channel_map=center,subwoofer channel_map=front-left,front-right
load-module module-remap-sink sink_name=virtside master=eightchannel channels=2 master_channel_map=side-left,side-right channel_map=front-left,front-right
Now when I create an output stream (I use mpd), I can see it
in pavucontrol, and I can see all five sinks. The only problem is that the
sinks are not labeled by their sink_names, but instead the first one is
"HDA ATI SB AD198x Analog", and all four others are labeled
"Remapped HDA ATI ...", which is kind of unreadable.
When I redirect the mpd stream to any of the above sinks
except the "virtcentersub", the sound is playing in all four output jacks,
only in the Center/subwoofer jack the right channel remains silent.
When I redirect the mpd stream to the "virtcentersub" sink,
all output jacks remain silent, except the Center/Subwoofer jack
now plays correctly both channels (which is what I expect it to do).
I have also verified that I have the channels in the "eightchannel"
sink set up correctly - when I move their respective sliders in pavucontrol,
I can hear the volume change of the correct channel of the correct jack.
So my question is - why the sound always plays to all channels
(except the right channel of the center/subwoofer jack) even when directed
through the module-remap-sink to only one jack?
Thanks,
-Yenya
