isto acabou por dar chatice!
novo caminho:

sempre como root.

apt remove firefox
apt edit-sources

remover os repositórios do sid

nano /etc/apt/preferences

comentar tudo o que tenha que ver com unstable

apt update

NÃO FAZER ISTO PORQUE PROVOCA CRASHES!

mkdir /lib/firmware/brcm/

[bluetooth] module-bluez5-device.c: Skipping 10841 us (= 1912 bytes) in audio stream

I was encountering this same issue on Gentoo. It appeared to be at random times but persistent once it started. I realized that it only happens if 'gnome-control-center bluetooth' is open. I would often leave this open after pairing the device, not really thinking about it. As soon as I close it the "module-bluez5-device.c: Skipping..." messages stop and the choppy sound goes away.

Posting in case it helps track this down.
