<pre>I plugged in my own usb surround sound card and tried your configuration, and I
didn't have the trouble you're describing.
When you observe the problem, what does "pactl list sink-inputs" print? Do both
of the module-remap-sink streams have the same index in the "Sink:" field (it
should be the index of the master sink)?
If the streams are routed correctly, you can check the mixing matrix from the
log. In the log you attached earlier, the matrix of the first remap sink looks
like this:
D: [pulseaudio] resampler.c: Channel matrix:
D: [pulseaudio] resampler.c: I00 I01
D: [pulseaudio] resampler.c: +------------
D: [pulseaudio] resampler.c: O00 | 1.000 0.000
D: [pulseaudio] resampler.c: O01 | 0.000 1.000
D: [pulseaudio] resampler.c: O02 | 0.000 0.000
D: [pulseaudio] resampler.c: O03 | 0.000 0.000
D: [pulseaudio] resampler.c: O04 | 0.000 0.000
D: [pulseaudio] resampler.c: O05 | 0.000 0.000
D: [pulseaudio] resampler.c: O06 | 0.000 0.000
D: [pulseaudio] resampler.c: O07 | 0.000 0.000
and the second one:
D: [pulseaudio] resampler.c: Channel matrix:
D: [pulseaudio] resampler.c: I00 I01
D: [pulseaudio] resampler.c: +------------
D: [pulseaudio] resampler.c: O00 | 0.000 0.000
D: [pulseaudio] resampler.c: O01 | 0.000 0.000
D: [pulseaudio] resampler.c: O02 | 1.000 0.000
D: [pulseaudio] resampler.c: O03 | 0.000 1.000
D: [pulseaudio] resampler.c: O04 | 0.000 0.000
D: [pulseaudio] resampler.c: O05 | 0.000 0.000
D: [pulseaudio] resampler.c: O06 | 0.000 0.000
D: [pulseaudio] resampler.c: O07 | 0.000 0.000
Those seem to be correct: the two input channels from the first remap sink go
to channels 0 and 1 of the master sink, and from the second remap sink they go
to channels 2 and 3 of the master sink.</pre>
