I believe the problem was that the codec and dac started out in some kind of low-power mode and needed to be woken up before they would work. Hopefully someone is still working on a proper driver, but for now, I can watch movies again! A diff against Andrea's work is attached. -- This .signature sanitized for your protection --0-1632943865-1152453933=:31266 Content-Type: TEXT/PLAIN; charset=US-ASCII; name=sigma.diff
