Connected Bluetooth Device Not Recognized as Au...

Short Version:

The device in question is connected according to itself and the Bluetooth Preferences, but does not show up as an output option in Sound Preferences.

 

Long Version:

I recently purchased an AmazonBasics Bluetooth Audio Receiver with the intention of being able to broadcast from my phone, MacBook, etc. to a pair of non-Bluetooth speakers from across the room. Most of my computer problems are self-inflicted, so I'd imagine this has to do with some changes I made a few months back that I will detail further down.

 

The computer experiencing issues is a 2012 MacBook Pro 13" (MacBookPro9,2), running Yosemite 10.10.5.

 

Here's what I know:

  • The device connects and shows up as a connected Bluetooth device in System Preferences.
  • The device is able to receive audio from my Android phone.
  • The device is able to receive audio from my 2010 MacBook Pro running the same OS version (10.10.5), less a security update and various app updates.
  • I had to manually remove Avid ProTools components a few months ago, so likely the issue is with something I edited incorrectly.
  • Copying com.apple.audio.SystemSettings.plist from the 2010 model to the 2012 model does not correct the issue.
  • Deleting com.apple.audio.SystemSettings.plist from the 2012 model outright does not correct the issue.
  • Restarting, etc. does not correct the issue.

 

I suspect that there is some kext file or similar package that needs to be reset or replaced with a good one, but don't know where it would be.

 

I do not want to (nor should I have to, in theory) reinstall my system due to a million and a half other reasons.

 

I realize that this is an unusual issue, as various search engines with various terms yielded nothing fruitful. Any assistance you can offer is appreciated.

Hi,

The problem you described just began happening to me . . . out of a clear blue sky, so to speak.  Everything had been working well in this regard . . . until it suddenly quit working, for no apparent reason.  My paired bluetooth device, which formerly worked fine with the MacBook Pro suddenly is no longer recognized as a sound output device.

 

Has anyone offered any help to you on this?

I experiences this same problem (paired bluetooth device not showing as sound output option), but the problem resolved itself the day after I reported it.  Unfortunately, I have absolutely no idea why or how the problem arose in the first place or how it resolved itself.  So if it happens again I'm still in the dark about how to deal with it.  I'd not restarted the computer.  Deus ex machina!?  More than a slight bit annoying/frustrating!  Any logical explanations for what's going on here would be appreciated.
