Device has 4 channels output, 2 channels input, but on mixer only 2 channels as
1x stereo is recognized as pcm, vol.
pcm5:record:dsp5.r0 can be accessed and used to record (at least works with
programs using audio/miniaudio), but is not listed on mixer(8)
2 more devices with similar behavior are available if logs would be useful.
