Is it possible to use module-combine-sink to combine a network PA device and a local device? I've been trying commands such as: $ pactl load-module module-combine-sink sink_name=Combined2 sink_properties=device.description=CombinedTwo slaves=tunnel.raspberrypi.local.alsa_output.usb-Focusrite_Scarlett_2i4_USB-00.analog-surround-40,alsa_output.usb-XMOS_HIFI_DSD-00.analog-stereo channels=2 Failure: Module initialisation failed Or sticking similar config into /etc/pulse/default.pa with no luck. I can use each device individually fine. I wonder if I'd have more luck trying to do this with Pipewire? I'd have to upgrade both machines before that is an option so I'd rather get this working with PA if its possible.
