add the following code to your main config
context.exec = [
{ path = "/usr/bin/pipewire" args = "-c /etc/pipewire/virtual_sinks.conf" }
]
pipewire configuration combining Headset and VR Headset audio into 1 device, and creating various sinks that get streamed into the combined device
this will give you all audio outputs at the same time so you can just reference the node.name
of whatever HDMI/DP Output the HMDI is attached to instead of having to select a particular output in pavucontrol
pactl -- set-sink-mute "alsa_output.pci-0000_11_00.1.pro-output-8" off; %command%; pactl -- set-sink-mute "alsa_output.pci-0000_11_00.1.pro-output-8" on
