Bluetooth audio problems Catalina

I've updated to Catalina and I'm not experiencing a lot of problems, but one problem in particular and it annoys me a lot.


I'm always using Bluetooth headphones or speakers on my Mac to listen to music.


The problem is that the sound to my output device randomly drops to zero. First I thought it lost connection but when I go to Bluetooth Settings it's still there and connected. When I go to Audio settings the device is still there and selected. So I push the volume-up button and the output device instantly changes to internal speakers and the sound is being played through my speakers instead of my Bluetooth connected device. When I look at the Bluetooth Settings again, the headphones are still connected. So it looks like an audio-codec-driver-software-hardware(or whatever it is)-problem instead of an Bluetooth problem. My Bluetooth apple mouse stays connected and keeps working.


The problem, as described above, appears randomly. Sometimes 3 or 4 times spread over the day, sometimes 4 or 5 times within an hour, sometimes 2 times within a minute! Very annoying.


The quickest way to solve the problem ad hoc is to disconnect and connect the Bluetooth device again through the top at Bluetooth settings.


I'm using different devices and each of them have the same problem;

- Apple AirPods 2

- Steelseries Arctis Wireless Pro

- Jbl charge 3


I've already deleted the Bluetooth folder in Library and rebooted my Mac.


I've already forgot the devices and reconnected everything.


I've already turned off and on my Bluetooth on my Mac


I've already turned off my Bluetooth on my phone (thought maybe this caused the problems but.. unfortunately no..)


Is there anyone with the same problems or does anyone has any ideas to fix this extremely annoying problem?


It looks like this problem appeared eversince I've updated my device to Catalina.

Same issues with 2 different sets of bluetooth headphones on MacOS 10.15.1. No other bluetooth items are connected. It doesn't happen as often as others are stating, but maybe once every couple of days or so.


It's annoying as **** when I'm rocking out in a coffee shop, and then suddenly my machine starts playing from the speakers... loudly. 😳

Hi guys I've been having this issue too, I use only bluetooth audio devices and they keep connected sometimes but are not selectable as audio devices, after seeing in many sites I didn't find anything that helped me to fix the issue and I realized it may be not a bluetooth problem but an audio problem since in Mojave I had a similar issue, so what I did as a partial solution is to reset Audio device from the terminal using one of these commands:


Mojave

sudo killall coreaudiod


Catalina

sudo kill -9 168


I hope they work for you

These actions presented by javotroya are too specific, and cannot work. You should rather find coreaudiod in Activity Monitor and kill it there. Otherwise, you can try a restart of your Apple computer. These actions are basically the same, except that the killing will cause problems when you restart. If you do the kill, the music will be interrupted for a short time.


I am not sure if this is going to solve the problem. Not for me.


I can only speculate in the soda/super user command, perhaps a user dilemma? I don’t have an answer.

Yes - what i've noticed on my headphones is that the "high quality stereo" bluetooth profile becomes disconnected so that music/sound output is redirected to speakers - HOWEVER my headphones are still connected on bluetooth but now on the "noisier 8kHz phone quality headset" bluetooth profile that you would be utilizing for skype audio, for example. So they are still connected to bluetooth in one mode but not the other. I hope that's helpful to apple developers troubleshooting the issue. I wonder if they've been able to recreate the issue or if they are even looking into it? I wish there was some official place they could acknowledge bugs and issues - if I wasn't so lazy I guess I should go up to the apple store.

A reply to all who have this problem!


I've contacted Apple Support and the Support Specialist helped me very kindly. We've runned some diagnostic tests on my mac. These reports have been sent to the developement department. He strongly recommended me to inform you all and if you experiencing this problem as wel, contact Apple Support. The more data they receive sooner the problem will be fixed.


So please report your problem to Apple Support and refer to this thread!

Sorry I should have been more emphatic in the PARTIAL SOLUTION phrase. Because it is not a solution it's a WORKAROUND while @apple solves the issue. The commands will only kill audio and then the system restarts it again that way you won't have to restart the whole computer. To me, it happens only during idle time even if there's music playing, being idle detaches audio from bluetooth and then I see the device connected on the bluetooth list but not as audio device selectable.


TL;DR


The commands are just a workaround
