Alas, I spoke too soon. The headphone jack and
internal speakers work as expected, until I adjust the
main volume (labeled in alsamixer as 'front') at which
point both the internal speakers and headphones play!
Unplugging the headphones and reconnecting them makes
everything OK again.
Any ideas? (patch against 2.6.22 that makes my chip
mostly work is attached). I guess that
alc262_hippo_automute() needs to be called somewhere
it isn't, but I couldn't see where.
Thanks again!
Andy
