I have a Zoom LiveTrak L-8 that is recognized in Audacity on Fedora 35 as 12 different channels. The first 2 are left and right mixdown of all the channels on the device. Channels 3-8 are the mono channels from mics and channels 9-12 are two stereo inputs on the device. However, if I run:
pw-cat -r --list-targets
Available targets ("*" denotes default): alsa_input.pci-0000_00_1f.3.analog-stereo * 48: description="Built-in Audio Analog Stereo" prio=2009 89: description="L-8 Multichannel" prio=2000
And running something like:
pw-cat -r --target=89 foo.wav
results in a foo.wav containing the first 2 two channels from the device ie. the mixdown of all channels.
Also when I navigate in gnome to
sound → ìnput Device` the “L-8 multichannel” is not in the list. Is audacity doing something on its own to recognize and use this device that is not dependant on pipewire or why is it that the device is recognized in these three ways?
