I hinted gpio1, which gives me sound from both speakers and
headphones.  Thanks!  There's still a few issues however:
 - Plugging in the headphones does not mute the speakers.
 - There's a speaker setting in mixer, but it doesn't work.
 - More problematic, the sound sounds like it's from a tape recorder
with low battery: it speeds up and slows down, seemingly randomly,
with a period of seconds.  Makes for bad-sounding music playback at
least.  This is a laptop, so I suspected powerd, but even disabling
powerd didn't seem to help.  Is there a buffering setting I should be
looking at changing?

Thanks,
Peter
