Ok, this could be nasty, assuming I should use the analog I/Os for some
reason, so I at least should get rid of passing inputs through to
outputs.
Not just that, my focusrite sounds crappy when the
outputs are "too
loud" in alsamixer. means over 80% its not usable. so maybe that is an
issue, Ralf?
I don't know if there is a less optimal bias point for the analog
domain, at least the audio source didn't cause a signal > 0 dBFS.
To patch the kernel, do I need to search an alsa / snd_usb_audio
source file to add the ID or is it somewhere else? ...
