There isn't a limit on sinks per-se, just whatever resources your computer has for resampling/mixing/etc. -- Arun ___ pulseaudio-discuss mailing list pulseaudio-discuss@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/pulseaudio-discuss

I just asked the wrong question... Sorry... What could help me, in my case, is to remap the mono sink-input (the ouput of my application) into a stereo one, so that I could control the volume of each channel with set-sink-input. Maybe I missed something but module-remap-sink doesn't like to do it. I tried to use module-remap-source but "Name or index of the master source" seems to concern sink listed with "pacmd list-sinks" not "pactl list sink-inputs". Is there a solution to get a stereo sink-input from a mono one ? There's no way to change the channel map of a sink input. It sounds like you could load one remap-sink for the left channel and one remap- sink for the right channel, and point the application to the appropriate remap-sink. A BIG THANK YOU ! It perfectly works ! I'm going to try in few days with many more sound cards but is there a known limit to the number of sink which can be create this way ? Is 40 something completely crazy to think about ?

It's exactly the command I was looking for. Unfortunately, as I thought, it doesn't work in my case because my output is in mono.
