I have a headset that has two output devices, a stereo and a mono, with a fade pot to go between them. This means I want voice programs to go to mono, and everything else to go to stereo.
I also have some speakers, and I would like to output to them at the same time.
The internet has a lot of suggestions, most of which boil down to “use use paprefs to output to every sink at once and make a device description wider than the entire monitor”
By actually reading the docs, I figured out that the
module-combine-sink can take a list of sinks to output to as an argument.
So what I have is
cp /etc/pulse/default.pa ~/.config/pulse
- list sinks with
pactl list short sinks
pactl load-module module-combine-sink sink_name=combined slaves=$sink_list sink_properties=device.description=whatever
- Once that works, put it in
~/.config/pulse, restart pulseaudio.
load-module module-combine-sink sink_name=combined slaves=alsa_output.pci-0000_01_00.1.hdmi-stereo-extra3,alsa_output.usb-SteelSeries_SteelSeries_Arctis_7-00.analog-stereo,alsa_output.pci-0000_00_1f.3.analog-stereo,alsa_output.pci-0000_00_1f.3.iec958-stereo sink_properties=device.description=combined-without-headphone-mono set-default-sink combined
Make sure that if you have to do stuff like setup which HDMI output you use for stuff like a VR hat that is done first.
Get card Name and Active Profile from
pactl list cards
set-card-profile alsa_card.pci-0000_01_00.1 output:hdmi-stereo-extra3
