Anyone who used this install method having trouble with the sound working out of their laptop? I changed it to internal speakers, etc. but no luck. Shows as being on too; that's the weird thing.
EDIT: Ignore that...looks like the notification that you're changing the volume no longer works. Sound still works though otherwise.
Installed DP5 over PB1, Sound works fine on my Mid-2011 Air. Volume Adjustment overlay appears on screen.
(Although I'm not a fan of the full opacity of the new overlay and dark "empty" bars.)
