QC35 plays sound from .mp4 file but not media from browsers
I have recently started having issues with my QC35s and MacBook Pro. All used to work OK, but in the last week or so I have found that the QC35 will not play sound from Firefox or from Safari when a webcast is playing, the sound comes from the main speakers. This is even with the headphones connected OK, and sound preferences saying output is QC35. If I change the volume in sound preferences I can hear the "bonk" in the headphones.
However, if I play a video file, a .mp4, the sound is played through the headphones OK.
I have tried clearing the bluetooth list and repairing but this hasn't made any difference.
I have also started having issues with the iPhone SE - I used to be able to just put on the headphones and turn them on for them to pick up the call, this has also become an intermittent thing. I even couldn't get the QC35s to connect to the phone at all yesterday when I wanted to make an outgoing call.
This is all really disappointing - I love my QC35s!
