(Pxl5) Audio via JBL speaker becomes fractured after some minutes

Question

The following is a consistent problem (reproduces always):

1. Connecting phone to speaker and turning music on
2. Music is played, un-fractured.
3. Within 30 minutes (maybe less), music becomes very fractured: most of the time you can't hear anything, once every few seconds, about one second bit of the music is played.
4. When awakening the phone (clicking any button), the music immediately returns for another fracture, then problem continues.

Models:

• Phone: Pixel 5, Android v. 12
• Speaker: JBL GO 2

Troubleshoot:

• Tried with another JBL GO 2 - problem persists.
• When using Jabra bluetooth earphones - problem does not persist.
• Didn't check for other speakers or bluetooth audio equipment.
• Didn't check for music players other than Spotify.
