Public bug reported:
Binary package hint: pulseaudio
I am trying to run my 5.1 surround card as two independent stereo
channels. In previous versions of Ubuntu (9.10 this still worked), I
have done this by adding the following commands to my
/etc/pulse/default.pa file. It appears to no longer work, allowing me
to add the first remap, but always crashing after the second remap
saying:
E: sink.c: Assertion 'PA_SINK_INPUT_IS_LINKED(st)' failed at
pulsecore/sink.c:1748, function pa_sink_check_suspend(). Aborting.
The relevant part of config is:
load-module module-remap-sink sink_name=headphones
master=alsa_output.pci-0000_00_1b.0.analog-surround-51 channels=2
master_channel_map=front-left,front-right channel_map=front-left,front-right
remix=no
update-sink-proplist headphones device.description=Headphones
load-module module-remap-sink sink_name=external_speakers
master=alsa_output.pci-0000_00_1b.0.analog-surround-51 channels=2
master_channel_map=rear-left,rear-right channel_map=front-left,front-right
remix=no
update-sink-proplist external_speakers device.description=Speakers
I can add one of these lines (either one), but adding the second will
crash. I've attached my default.pa file and the logfile produced by
attempting to start the pulseaudio service with -Cvvvv
