 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).
