Hey guys. I created a echo-cancel sink as described in the wiki: https://wiki.archlinux.org/index.php/Pu … ancelation
Now I recognised that my headphones dont distinguish between left and right. I checked it with pacmd list-sinks and the sink is configured to mono.
I tried to set the channels and the channel_map with the options as shown here: https://www.freedesktop.org/wiki/Softwa … #index45h3
After restarting PulseAudio it still was set to mono. Just the use_master_format option set the channels and the mapping to stereo, but than there was no difference between the sound with and without sink.
Any suggestions?

try when you create the echo-cancel sink to use
format=s24-32le channels=2
do check in pacmd list-sinks under sample spec what sample your sinks use by default (for me it is s32le)
also you can try using
use_master_format=true
this might also work but never tried it myself
