Err, disregard this comment, of course :)

AFAIK, ALC268 doesn't use GPIOs for EAPD controls but only EAPD
verbs.  So, setting EAPD on the widget should suffice.

Anyway, it'd be better to show codec#0 proc at the state you believe
that you've set up correctly but no sound comes out from the speaker.
Also, clarify what you've tested, too.
