Created attachment 273678

improved patch

I improved the patch. The handling in uaudio_attach() is actually useless
because audio_rev is fetched in uaudio_mixer_fill_info() only. I just swapped
the udev argument for uaa. Can you test this on the "main" branch? Otherwise
you'll need to modify it a bit.
