Public bug reported:
Here's my issue.
My internal speakers work fine and even mute when i plug my external speakers
in the headphone jack. However i have no sound coming out of my external
speakers when plugged in. i checked my levels and everything is fine and
unmuted and the sound settings even show "headphones" in the output tab but
when i test them i get nothing. at least this is a step up from 11.10 where
the internal speakers would not mute and wouldn't even recognize the headphone
jack. i've tried all the recommended
options snd-hda-intel model= settings and nothing. when i put in imac27 the
system doesn't mute the internals and doesn't recognize my headphone jack at
all.
any help would be great.
thanks...
