First patch on its own - alc-no-primary-hp-out.diff - fixes the bug.
Output through the speakers works. I also tested that it doesn't do
anything bad to the speaker/headphone output: plugging in headphones
routes the output through that socket automatically, no need to change
any PA setting, and unplugging the headphones sends it back through the
internal speakers again. The internal mic works fine in all cases. So
with just the first patch, everything works correctly as far as I can
test (I don't have an external mic to check).
Didn't try the other patch on its own or in combination yet. I'll do so
tomorrow, unless you tell me it's not necessary. Thanks!
