Multipoint Bluetooth audio issue

[movisman]

Hi there,

As per this thread:
https://forums.linuxmint.com/viewtopic.php?f=49&t=294078

On LM19.1, if I have a device connected which supports simultaneous connection to two devices at once (tested with Jabra and Bose headphones), on Linux Mint the sound is exceptionally choppy and causes instability. Disconnecting both devices, and reconnecting JUST the PC running Mint resolves the issue. As soon as you connect the second device, the issue starts.

See my post on the above thread for more details on the issue.

This issue does not happen with other Ubuntu deriatives, eg Kubuntu, Ubuntu MATE 18.04, but I understand these use Blueman instead of Blueberry for Bluetooth management.

As MrEen kindly suggested in the forum, it was suggested I remove Blueberry and install Blueman. I did that and this specific issue went away. Bluetooth headphone implementation with Linux still has a few other issues of it's own but this multipoint thing I experienced seemed exclusive to Mint.

This indicates (to me) that the problem is somewhere in Blueberry, because using Blueman doesn't have the issue.

Hopefully this is ok to raise here, maybe someone can take a look at it when they have time and see if they can replicate it.

Thanks!

I tried reproducing it on Fedora 31 with blueberry 1.3.3. I have a Jabra Evolve 65 headset that supports two paired devices. I connected an Android smartphone and a PC and I can't hear any issues with the sound. You never mentioned which blueberry version you were using (and pulseaudio and kernel, either).
