mics: "Internal Microphone" is basically unusable and full of noise (like
an unplugged non-internal microphone), and "Microphone" works fine as if
always plugged (like an internal microphone), though pulse reports the
contrary.

do you mean this patch still don't fix the internal mic ?

in 5.1 surround sound.
