Hi Takashi,

Great to see these improvements! I have a question about this patch:

There are three ways we can auto-mute:

Headphones might mute Internal Speakers.
Headphones might mute Line out.
Line out might mute Internal Speakers.

Are we considering the third option here or is that still unsupported?

Also, it might be slightly confusing for the end-user to have options 
that are irrelevant, e g if there are no internal speakers (or line-out 
for that matter), that option will still show up. Right?
