I have Fedora 34 installed (Linux BLUE-FEDORA34 5.11.15-300.fc34.x86_64). I have a pre-existing hardware issue with my audio where one of my channels is broken. As a workaround, I just downmix the stereo audio to mono audio (i.e. combine the left and right audio source before outputting the same thing to left and right output).
With pulseaudio, I used to follow this guide here: sound - Can I downmix stereo audio to mono? - Ask Ubuntu, but now that pulseaudio has been replaced by pipewire in Fedora 34, I imagine these instructions don’t apply anymore:
pacmd load-module module-remap-sink sink_name=mono master=$(pacmd list-sinks | grep -m 1 -oP 'name:\s<\K.*(?=>)') channels=2 channel_map=mono,mono
What would be an equivalent/alternative approach for pipewire?
