Bluetooth audio problems Catalina

Just comment to inform I'm having the same issue as well.

I'm running Catalina 10.15.4 and the problem happens with my Bose QC35 II. The bluetooth still connected, but sound output changed to Internal Speakers. I can see the Bose QC35 II option but doesn't let me change to that audio output. I have no issue with my bluetooth mouse or keyboard (they are not all connected at the same time btw, only headphones and mouse or just the headphones themselves)

After upgrade to 10.15.4 - still stuttering sound on AKG Bluetooth headset, as long as the Magic Mouse is connected as well. I disconnect the little pet - perfect sound. No issue with the touchpad though

It's now a few days later with constant use and I still haven't had a disconnect, even with a magic trackpad and a separate Logitech bluetooth mouse connected. I have had some issues with the mic input volume, sometimes not being able to speak in meetings, but I think that might be due to a specific conferencing app, which might be a little overloaded at the moment. With Microsoft Teams I've had no problems at all.

I found a fix for this issue, forcing BT to use audio codec aptX fixes the issue.

Please follow instructions on

Voyta, thanks a lot for this! Forcing aptX as decoder didn't solve my issue, but the Audio Graph showed an issue with transmission rates - and deselecting "force use of aptX" seems to have reset and my issue of stuttering sound in the BT headset is gone

Having watched quite a few people comment that 10.15.4 resolves the bluetooth disconnection issue, I decided to take the plunge and upgrade to Catalina ... again. Unfortunately I'm experiencing the same as GF95 reported above. After a couple of days the bluetooth audio disconnects are back, but the difference between the original issue and now is that bluetooth audio will reconnect after about 10-20 seconds. Before the reconnect completes audio is being played through the internal speakers.

To be clear, I was experiencing the issue originally reported on this thread, where audio would stop playing through a bluetooth device, although the device was still displayed as connected, and audio would be transferred to the internal speakers. Imho some of the comments on this thread mention issues that are similar but not the same, and it may be that these have been fixed in the 10.15.4 release.

I will be rolling back to Mojave ... again. Glad I took that backup!

I'm running 10.15.4 and I never had a problem until this version, and now it happens ALL the time, usually when using Webex, and both with wired headphones AND the internal Mac audio (the speakers and microphone sometimes just disappear altogether. Could it have anything to do with Webex, or using an HDMI external monitor with speakers (which I never use), or anything else?

I have a problem that seems to be related to this thread. I have a Mac Mini (2014) running Catalina 10.15.4. After the recent (for me) switch from Itunes to Music, when I connect via Bluetooth to a Sony receiver (Model STRDH190) I get a very annoying "squelch" noise at the beginning and end of every song played. This doesn't occur with other sources of music, only my Itunes (now Music) library. I've tried deconnecting, turning off, restarting, all bluetooth devices and have rebooted the computer numerous times. the problem occurs even when the Sony receiver is the only bluetooth connection. I am not a developer so "solutions" that require Apple developer access seem daunting (and unnecessary). Please is there a non-developer fix to this annoying problem?

This issue happens with my Airpods Pro and my Sony over-the-ear while using Zoom and Discord and this occurs on my personal and work Macbook Pro 10.15.4. It really impedes my productivity as I am missing virtual meetings at this point.

Same issue!

MacBook Air (13" Early 2015)

MacBookPro (15" Mid 2014)

MacOS Catalina Version 10.15.5

Using both Sony and JBL speakers, randomly the sound glitches or the device disconnects and reconnects. On iPhone XS and iPad Air 2 4G works without any throuble.

Same problem here: BOSE QC35 headphones, everything worked in Mojave, just updated to Catalina and headphones only remain connected for a few seconds then disconnect. I have tried all the suggestions.

They solved most issues for the most people. Works like a charm now (compared to 3 years ago for example), no any problems at all (Bose, Sony, Airpods, JBL). But of course it's not for everyone, there are a lot of different Macs and different BT devices. For example I have old Mac mini with BT 4.0 that I won't even use for BT sound, since BT 4.0 is disaster compared to BT 4.2 or especially 5.0.

These discussions are not for Apple support, they are for usual people, like us. I also waited to their reply, but it's not right place to do. The right thing is to write to their feedback form or call them.

I was having a similar problem with my Soundcore Flair. It would connect via Bluetooth, but the sound would not be redirected to the Soundcore speaker. If I did certain "magic" that I have no idea what it was, I could get it to work. Once it started working it usually continued to work, but not always.

Today I connect my Soundcore directly to my MacBook via USB. I have no idea what happened, but now the speaker won't even turn on.

Oh, I suppose it might be important that my battery swelled and I sent it into Apple last month. They upgraded it to Catalina (sadly) and ever since I cannot enumerate al the problems I've been having. I just updated to 10.15.6

I had Catalina version 10.15.6 installed and updated a little over a week ago and just now tried to pair my Pioneer SE-MJ553BT-K Overhead earphones to my MacBook Pro 15" 2017. Had no trouble with Mojave but Catalina is a no go. Is there an update by Mac to solve this issue!

I always regret updating OS too soon. No idea why I did this time. I just like the name Catalina I guess. Ever since I did my monitor speakers I use for video editing (and any other bluetooth speakers) judder and just don't work properly. Intensely annoying this isn't exactly new tech. Have tried resetting the bluetooth and all the usual suggested fixes. Desperately needs sorting, sound is rather a large component of a computers uses I find.
