whenever working with a song and i put the Mac to "sleep" and when i come back, "wake" the Mack, i see my G B project is still on the screen. whenever i try to playback my song there is no sound coming from my speakers or phones. i can see the sound "jumping" in my master track but i can't hear anything. i've checked all my config settings (drivers, input, output etc) and nothing seems to have changed . i also use Reaper as a DAW and see the same prob with it. the ONLY way i've found to get my sound back is to reboot the Mac, open Reaper (or G B), load my project and "wah lah" i've got music again. i have Reaper ver 4.581 and GarageBand 'll (ver 6.0.5 [428.5] ) and the Mac is ver
10.9.1 [ maverick]

Anyone know what's going on here - would sure app a reply if you do.
