sudo killall coreaudiod

this command will force core audio to restart, just had my audio drop in the 11R and did this command in terminal, its back up. Ive been on the hunt for terminal commands to drop and restart the 11R, but im thinking this is also a core audio ordeal, and im not certain that the 11R is really meant to be used without a host interface. If it were then the driver might stay engaged even after sleep mode
