I have exactly the same issue as angry.sardine there: after the installation of a2dp, I paired my Plantronics headset to the vero4+ easily but I have no sound at all and the video freeze after a few seconds.
I already removed a2dp, installed it again, reboot several times Vero,… No joy.
What can I do? (and please, be very clear: I’m quite a noob and English is not my first language).
If I understand well, I have now no pulse and no a2dp. But if I’m able to pair my headset with Vero, the indicator is red : it fails to connect. And consequently I have no sound in the Plantronic s(but no freezing of the video)…
I tried to install again a2dp but it install also pulse with the same behavior as previously: pairing and connction successfull but no sound and freezing of the video after a few seconds.
I sincerely think you should put “Bluetooth is experimental” in the blurb about the 4k/4k+ so that buyers are aware they can’t / may not be able to use their bluetooth headphones or speakers.
I have exactly the same problem as the OP, except with sony headphones. It works about 10% of the time and only after several reboots and several pairing / unpairing options. Freezing audio, screeching sound or no sound is usually what happens.
Despite all the good things the vero can do, this has been a problem for ages with no permanent solution. I had hoped with the recent big update that this problem will finally be resolved.
As suggested I tried connecting a Bluetooth speaker with the command line (after a pulse/a2dp purge): no joy. The pairing seems ok but not the connecting. And no sound at all.
One solution is to use a Bluetooth dongle provided with the headset. But I can’t: I use 1 USB port for the remote and the other for an external disk.
To sum up, I’ll continue with a jack connected headset. Thanks for your time, and if you plan modifications, I’ll be happy about it.
