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.
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 not recognized as an audio device on my 2012 MacBook Pro (it doesn't show up in the preferences pane).
- 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.
MacBook Pro (13-inch Mid 2012), OS X Yosemite (10.10.5)
