Mojave DP4 Bluetooth Audio problems

Just wondering if anyone else is having bluetooth audio problems since installing DP4? My bluetooth headphones (QC35) connect fine and show up as an audio output source but no audio plays (just silent regardless of volume setting). Same with connecting a UE Boom bluetooth speaker as well.


Was working fine a few days ago so I assume its the latest update but not 100% sure.

I'm having the Same Problem.


My Airpod is connected successfully, but I can not hear any sound at all.

Same ...

I've been having the same problem with my QC35 since public beta 1.

I have same problem on build 18A336e.


In logs:

bluetoothaudiodError sending audio packet: 0xe00002c2
bluetoothaudiodEncoding is failing with e00002c2
bluetoothaudiodUnable to create the AAC encoder
bluetoothaudiodEncoder error 1

Same thing is happening to me on 18A336e. Macbook pro 2017. Tried airpods and my old LG bluetooth set, both give no audio despite showing being connected.

Seeing this as well with similar bluetoothaudiod errors in the console.

Same here with AirPods and other bluetooth headsets

Same here Powerbeats3

Same here with Beats Studio 2

Same for me with a set of Bose QC35 headphones. I'm on Mojave dev beta 18A336e.


Symptoms in case it helps anyone:


  • headphones connect as normal in system
  • itunes connects to them as normal also
  • hardware volume controls move the onscreen slider in system prefs
  • playing music via itunes: no sound
  • playing a youtube vid: no sound
  • headphone name intermittently changes between '<headphone name>' and 'LE-<headphone name>' in bluetooth prefs
  • using option click on the bluetooth tray item > headphone name I see 'active codec: SBC' while sound is playing but there is no audio
  • if I go to sound prefs > input tab the music will start playing but sounds low quality. I notice 'Active Codec: SCO' while on this tab.

I have the exact same problem with AirPods but my Bowers & Wilkins PX works fine. Also running dev beta 18A336e.

I also just tried it with Jabra Rox, Beats Solo3, and the Sennheiser MM400. All of them have the exact same problem as the AirPods. It's strange how only the PXs work. 😕
