Hmm, interesting. Any idea which of the two combines this message is coming from? > Dec 21 11:19:06 rebirth pulseaudio[14764]: module-remap-sink.c: No > remapping configured, proceeding nonetheless! There appears to be a typo in your last remap where you have "channel_map=left_right" when I presume you mean "channel_map=left,right" > then, despite the fact that it says it's proceeding, it simply proceeds > to exit with no further log entries. Hmm, interesting. Can you run manually via pulseaudio -vvvv (with the appropriate --system argument - you'll have to run as root and it should drop privs to the "pulse" user) > So you may ask what I'm trying to accomplish.

One potentially easier (but maybe not as nice?) way would be to create a null sink with a single channel then use module-loopback sink to connect it's monitor to your real sink. It should automatically upmix the mono null sink to stereo on your real sink.... not 100% sure this will work but it should do.
