Here's what I've got so far based on my revisions: > https://imgur.com/NzteBvg > > Step 1: Create the music_mic_mix virtual mixer > $ pacmd load-module module-null-sink sink_name=music_mic_mix > $ pacmd update-sink-proplist music_mic_mix device.description=music_mic_mix Looks good. To help out discovery later on, you can also run this command to give the monitor source a better name: $ pacmd update-source-proplist music_mic_mix.monitor device.description=music_mic_mix.monitor > Step 2: Create the mic_loop loopback module and specify the sink as the > virtual mixer created in step 1 (music_mic_mix) > $ pacmd load-module module-loopback sink=music_mic_mix If you want to be more automated, feel free to specify a source= here pointing to your microphone's source if you know it's name. You can figure out the correct name with the "pacmd list-sources" command. > Step 3: Create the music_only virtual mixer > $pacmd load-module module-null-sink sink_name=music_only > $ pacmd update-sink-proplist music_only device.description=music_only > > Step 4: Create the music_loop_headphones loopback module and specify my > headphones output as the "real sink". (I found the name using the pacmd > list-sinks command.) > $ pacmd load-module module-loopback > sink=alsa_output.usb-Plantronics_Plantronics_BT600.analog-stereo The source here can be specified. Since we're using the auto-monitor source from the music_only virtual sink, the format is virt_sink_name.monitor. For example: $ pacmd load-module module-loopback sink=alsa_output.usb-Plantronics_Plantronics_BT600.analog-stereo source=music_only.monitor > Step 5: Create the music_loop_videoconf loopback module and specify the > music_mic_mix created in step 1 as the sink > $ pacmd load-module module-loopback sink=music_mic_mix Same deal. Add "source=music_only.monitor" to the command. > Step 6: Connect the headset microphone to the mic_loop loopback module via > the "Recording" tab in pavucontrol. It's possible to skip this if you did what I mentioned in reply to step 2. > Step 7: Direct the output of Rhythmbox to the music_only virtual mixer > created in step 3 via the "Playback" tab in pavucontrol. Yep. > Step 8: Direct the output of the music_mix_mix virtual mixer created in > step 1 to the video conference application in the "Recording" tab of > pavucontrol. Yep. If you ran the extra command I mentioned in step 1, this should have the name music_mic_mix.monitor. Also, if the recording app doesn't try to muck with things, pulse will remember and re-apply your selection whenever the recording app is launched. > My question is how do I direct the output of the music_only virtual mixer > created in step 3 to the music_loop_headphones and music_loop_videoconf > loopback modules created in steps 4 and 5 (indicated by the red boxes in my > revised diagram)? Hopefully the above helped. While verifying that this works, I created the following shell script. You'd have to swap the hardware sink/source names, but it does work: #!/bin/bash # Step 1: music_mic_mix virt sink pacmd load-module module-null-sink sink_name=music_mic_mix pacmd update-sink-proplist music_mic_mix device.description=music_mic_mix pacmd update-source-proplist music_mic_mix.monitor device.description=music_mic_mix.monitor # Step 2: mic_loopback pacmd load-module module-loopback sink=music_mic_mix source=alsa_input.pci-0000_00_1b.0.analog-stereo # Step 3: music_only virt sink pacmd load-module module-null-sink sink_name=music_only pacmd update-sink-proplist music_only device.description=music_only pacmd update-source-proplist music_only.monitor device.description=music_only.monitor # Step 4: loopback for headphones pacmd load-module module-loopback sink=alsa_output.pci-0000_00_1b.0.analog-stereo source=music_only.monitor # Step 5: music loopback for videoconference recording input pacmd load-module module-loopback sink=music_mic_mix source=music_only.monitor # Step 6: already done in step 2. # Step 7: Play music to music_only virt sink # Step 8: Record from music_mic_mix.monitor _______________________________________________ pulseaudio-discuss mailing list pulseaudio-discuss@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/pulseaudio-discuss
