Hi, after I upgraded to big sur, my headphones (and other bluetooth audio devices) don't turn up anymore on the sound coontrol window. It does pair, but cannot select in-output. Only internal and airplay devices...
Already debugged bluetooth (shift-option click on bluetooth icon) but didn't help. Anyone else with same problems or a solution?
MacBook Pro 15″, macOS 10.15
Sorry!!!,
I was too quick with posting. Just removed devices and paired them again. And... It works!!!
Thank you very much!!
I was able to fix the problem with the following steps:
Hopefully this works for you. It was a huge relief for me.
Hi Vincent, sorry for my late reply but mu MacBook was at the repairshop for a new battery. I picked it up just yesterday and tried your solution right away.
Unfortunately it did not help. I receive an illegal option message. I understand absolutely nothing about terminal so don't know where to go from here...
This is the message:
