Whenever I turn on/off my bluetooth headset, my RAM previews no longer play back. I can see the green bar progressing, but nothing updates in the Comp window. When I hit "space" or "0" nothing happens. Then, if I go to Preferences > Audio Hardware and change the output to my speakers or back to the newly turned on bluetooth, everything works fine again. I've also had it when I didn't change anything with my audio devices and the previews stop working, but going to Audio Hardware and just clicking back and forth on options there usually fixes it.
