Ram preview won't play
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.

Audition handles this better. It gives a bunch of prompts when audio devices connect / disconnect (which can be turned off), and those prompts allow you to open the Audio Hardware or System Audio Settings panel to select the desired input / output devices. If you just ignore all those prompts, audio will start playing back without any further intervention once Bluetooth is re-established.
With AE, you're required to change settings - it won't reconnect to the same device when it returns without manual intervention. It's such a frequent issue that I've mapped Audio Hardware to a hotkey. I have to do this several times a day, in the morning when I start my machine and any time I come back from a break long enough that I turned off my headphones to keep the battery fresh. If this were 3DS Max, I'd have put together a Macroscript to reconnect automatically or with a single hotkey press. I don't think AE has that level of scriptability (or I just don't know how to accomplish it).
Fixing this would be a major quality of life improvement.
