Title:
MacBookAir6,2, No sound though speakers
Status in “alsa-driver” package in Ubuntu:
Confirmed
Bug description:
Hi there,
There is no sound from the Mac's internal speakers. Audio interface is
detected in pulseaudio and sound works through the headphones jack.
Adjusting the volume displays the volume control bar correctly, but it
has no effect.
