Lost of bluetooth audio when multi-paired on a laptop

[Daniel LaSalle]

On a laptop running latest everything and paired with a wireless bluetooth speaker it happens after many days of usage (laptop on, goes into sleep mode, wireless bluetooth speaker is on, goes into sleep mode, gets powered off, goes into sleep mode again, gets paired with another device, etc) that Celluloid is loosing the audio profile.

Meaning:
1. play video, pause it;
2. close speaker;
3. pair it w/ another device, use it;
4. sometimes when you repair the speaker w/ the laptop and resume the video that there is no sound in Celluloid. The solution is to open up FireFox, play a video online and the sound will work again when resuming Celluloid play session.

This does not happen immediately after switching pairing of wireless bluetooth audio speaker. It does not appear often.

Lastly I have been using this setup for many LTSes and short term support Ubuntus and it never happened until 23.04.
