Both are based on v4.7-rc1. v4.6 worked ok for me.

Lets test mini-v4.7: in-call speaker works ok there, and no alsactl
warnings.

mini-v4.7+cb7e62256e99d285e415cf75db67558f0f8bb107+6d2de5ab4328718302c54b20222c6b1a574c3fce
: something seems to be broken there already.

alsactl: set_control:1464: Cannot write control '2:0:0:TPA6130A2
Headphone Playback Volume:0' : Remote I/O error

But in-call speakers and wired headset still seems to work.

Lets test mini-v4.9... works ok. I don't even get the remote i/o
error. Interesting.

So regression seems to be between v4.9 and v4.10. Any ideas?
