Hi Takashi,

> OK, then try the patch below.

Great - that patch seems to do the trick, the speakers now are working
perfectly :)

One question - what is supposed to be responsible for muting the
speakers with the headphones plugged in? I can switch between
headphones and speakers with pavucontrol which works fine (alsamixer
shows it simply mutes the speaker control when headphones are
selected), but the speaker is not being automatically muted when
headphones are plugged in - is that something that the driver is
supposed to handle, or is that a userspace problem?
