Comment # 10 on bug 1186648 from Takashi Iwai

Hrm, it's a pity that we have too short time for debugging.

Unless we get a test hardware, it's impossible to debug and fix it.  Hopefully
it'll get fixed in the upstream, then TW will work out of the box.

Closed as WONTFIX for now.  Feel free to reopen if you have a chance to
test/debug again.  Thanks.
