Mojave bluetooth connection -- audio issues

Hi There,

I had connection problem with my Sony H900N over the ear headphone. I tried to reset the headphone, it didn't help. Then I reset it to factory settings. It connected right away. Hope it helps.

cheers

Hi there,

after reading through all posts looking for a solution I could not find any that works for me. I have a MBP mid 2012 and Jabra 65t wireless in ears, the music often cuts or stops altogether. I have Mojave 10.14.1 installed, tried SMC and PRAM reset, did not help either.

Am I the only one who also has the problem of even choppier audio when sitting further away from the computer than 1m (3 feet)?

Is there a way to boost bluetooth power output?

I actually found the solution to my problem:

Mojave was falling back on SBC (low energy bad quality bluetooth standard) instead of higher quality AAC or AptX.

To force use of AAC to the system you can enter use terminal:

sudo defaults write bluetoothaudiod "Enable AAC codec" -bool true

To force use of AptX to the system enter:

sudo defaults write bluetoothaudiod "Enable AptX codec" -bool true

there is still another way described in the following article:

cheers

Sorry, but that answer STILL did not work for me with my 2016 MacBook Pro and Mojave.

My ER-19 wireless earbuds STILL show Codec as SBC, even after entering the two lines into Terminal.

And of course, the stuttering on playback continues.

No such issues with my iPhone 6.

OK... well I'm a persistent one...and I found out what worked for me. I turned OFF my Apple Magic Mouse 2 and VOILA...the earbuds work just fine with my MacBook Pro and macOS Mojave. Of course, I'm stuck using the trackpad on the MBP, but at least I know they work with the Mac.

Have tried all the above, nothing seems to help. My BBT Pro headphones keep switching on and off. The odd time it stays on, the audio only comes through one channel (left). My Sony 1000XM2 do connect, however they sound as a sixties transistor radio.

The strange thing, though, I didn't have this issue immediately after upgrading to Mojave. I don't know what triggered it, though. Perhaps a smaller upgrade later on?

Very annoying.

My supposed solution actually did not solve the Problem for one of my bluetooth speakers, which can only handle SBC.

So I found another article (in German: https://www.macwelt.de/a/14-typische-mac-probleme-und-ihre-loesungen,3438768) which helped me, I think the method was described somewhere above.

You have to punch in a few lines in terminal to increase Bluetooth energy output:

defaults write com.apple.BluetoothAudioAgent "Apple Bitpool Max (editable)" 80

defaults write com.apple.BluetoothAudioAgent "Apple Bitpool Min (editable)" 80

defaults write com.apple.BluetoothAudioAgent "Apple Initial Bitpool (editable)" 80

defaults write com.apple.BluetoothAudioAgent "Apple Initial Bitpool Min (editable)" 80

defaults write com.apple.BluetoothAudioAgent "Negotiated Bitpool" 80

defaults write com.apple.BluetoothAudioAgent "Negotiated Bitpool Max" 80

defaults write com.apple.BluetoothAudioAgent "Negotiated Bitpool Min" 80

sudo killall coreaudiod

the last line will kill your audio daemon after asking for your system PW. coreaudiod restarts automatically, at least in my case it did.

I'm also having the problem with JBL bluetooth connection. After Mc OS updated to 10.14.2 (18C54) Mojave. My JBL speaker is choppy all the time. Is it bug for this new version OS? What can I do now?

I too am having bluetooth issues. I did a clean reinstall and it worked for a short time then returned. If I use my iphone via bluetooth or plug in via headphone jack, my speakers are richer and louder. When I use the bluetooth on my MacBook Pro, the sound is far less. Any suggestions?

Although I thought I found a solution to my problem twice, the stuttering returned after some time.

I went back and deleted the Bluetooth preferences file (com.apple.Bluetooth.plist) in directory

/Library/Preferences/

and restarted my machine.

For now bluetooth works great.

I toggled between input and output devices. I changed my sound input to be the "Built-in Internal Microphone" instead of using my Blutooth speaker as sound input device, I maintained my SRS-XB3 speaker as the sound output device. Everything is working fine now, sound is excellent.

I have the same issue. I have been putting off upgrading, but finally did it this past weekend. Now when I try to listen to videos/music on my bluetooth it cuts in and out. It works fine if I listen with regular plug in ear phones. I have no idea how to fix it and I'm not very tech smart so I need step by step help. Do I need to make an appointment with Apple store to get them to fix? This is very annoying because I use my bluetooth all the time.

This is a hardware failure. The bluetooth module is defective. Apple is aware but they will never admit it. If you want to solve, buy a bluetooth dongle or a logitech mk850 keyboard or mouse combo or similar

I reverted back to High Sierra and I was able to get things back to normal. However, I will state that if you're a podcaster or use any audio capture software such as Loopback Audio or Audio Hijack by Rogue Amoeba, you should attempt to turn off that software. There appears to be a bug where if Loopback Audio has iTunes setup as a virtual device--even if it's not enabled, it can still hang on to the audio stack. In High Sierra, I was able to turn off Loopback and get my Bluetooth headphones working with iTunes.

I am having a similar issue. I am currently running Mojave and my powerbeats 3 won't connect. I have tried resetting the bluetooth module, and reseting my headphones but nothing is working. The loading sign is always next to "connected" and then after a few seconds it says connection failed. Any ideas on how to fix it?
