Hi Raymond, David.

Agreed, but on this model it feels like there's a mix-up between both 
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.

Yes! I mistyped it, sorry. Here is my alsa-info.sh, feel free to ask for 
more info: http://hastebin.com/kaleqeqibo.vhdl

Okay, following up with Raymond Yau, who asks me my alsa-info.sh

Commenting didn't work, but I added 'state.plugged = yes' and
'state.unplugged = yes' to the [Jack Mic] section for the input I want. 
Now it is always detected as plugged and the priority thing works :)
Thanks!
