Earlier I had trouble getting remapped sinks to work (ticket
#425). Now I decided to give it another try with pulseaudio
0.9.19. The bug is perhaps not the same, but the problem still
remains.
Sometimes it segfaults, especially when I try to switch to one of
the virtual devices in gnome-volume-control. Unfortunately I
haven't managed to get a core dump.
Sometimes it fails with an assertion at startup. It is irregular,
but very common when I frequently restart pulseaudio for testing
and tracking down this problem.
I've tried two different varieties:
First essentially the example in
<http://www.pulseaudio.org/wiki/Modules#module-remap-sink>:
load-module module-remap-sink sink_name=front_stereo master=output
channels=4 channel_map=front-left,front-right,aux0,aux1
sink_properties=device.description="FrontStereo"
load-module module-remap-sink sink_name=rear_stereo master=front_stereo
channels=2 master_channel_map=aux0,aux1 channel_map=front-left,front-right
sink_properties=device.description="RearStereo"
This one now fails consistently with a segfault, but I cannot
find any coredump (and I've disabled the coredumpsize limitation
in the shell).
I also tried a slightly different approach:
load-module module-remap-sink sink_name=front_stereo master=output
channels=2 channel_map=front-left,front-right
sink_properties=device.description="FrontStereo"
load-module module-remap-sink sink_name=rear_stereo master=output
channels=2 master_channel_map=rear-left,rear-right channel_map=front-left
,front-right sink_properties=device.description="RearStereo"
This fails most of the time with an assertion error (see attached
log).
