Hi, You could tel your iMac not to sleep. So, in the Energy Saver pane of System Prefs, check the box that says something about preventing your Mac from going to sleep when the display is off. When set in this fashion, the display will still dim or go to sleep, but your computer will remain awake.

On my iMac27 running Yosemite 10.10.3, it happens with an USB sound Card, Tascam US4x4. It's very annoying because when I wake up the computer from sleep, there is no more sound output. Any help?
