I also need to hear my piano in the headset (it has no speakers) I've based myself off of <a href="https://unix.stackexchange.com/questions/576785/redirecting-pulseaudio-sink-to-a-virtual-source" rel="noreferrer" target="_blank">https://unix.stackexchange.com/questions/576785/redirecting-pulseaudio-sink-to-a-virtual-source</a> and been testing all kinds of combinations, but I'm hitting a roadblock. The commands I'm using at the moment are: HEADSET="alsa_output.usb-Plantronics_Plantronics_Blackwire_3225_Series_1129BBD004004FF4BD2E6F2248C0D73E-00.analog-stereo" MIC="alsa_input.usb-Plantronics_Plantronics_Blackwire_3225_Series_1129BBD004004FF4BD2E6F2248C0D73E-00.analog-stereo" pacmd load-module module-null-sink sink_name=mix-for-virtual-mic sink_properties=device.description=Mix-for-Virtual-Microphone pacmd load-module module-combine-sink sink_name=virtual-microphone-and-speakers slaves=mix-for-virtual-mic,$HEADSET pacmd load-module module-loopback latency_msec=20 sink=virtual-microphone-and-speakers source=$MIC pacmd load-module module-null-sink sink_name=silence sink_properties=device.description=silent-sink-for-echo-cancel pacmd load-module module-echo-cancel sink_name=virtual-microphone source_name=virtual-microphone source_master=mix-for-virtual-mic.monitor sink_master=silence aec_method=null source_properties=device.description=Virtual-Microphone sink_properties=device.description=Virtual-Microphone The effect is that I can perfectly pick the microphone "Virtual Microphone" in the conferencing apps, but only my keyboard is sounding through. My voice / mic never gets picked up. I've tried recording using parecord --channels=2 -d mix-for-virtual-mic.monitor /tmp/x.wav but same story, only the piano is being picked up. What did I miss? In all logic, this should work?
