Connecting to bluetooth speaker, Rapidly Connects and Disconnects

My bluetooth speaker works fine with windows 11 and android phone. But it can’t work with Jetson Orin Nano v6.0 Jammy.

I did google around, but it seems little help.

Hi,
Please apply this:

Enabling Bluetooth Audio — NVIDIA Jetson Linux Developer Guide 1 documentation

  1. Speaker said “connected” by internal audio.
  2. App gave status “connected”.
  3. UI system setting showed “it was disconnected”.
  4. And I can’t connect the speaker by push the UI button “Connection” (I have to reboot the speaker, then loop back from 1-2-3-4)
  5. There is no audio from speaker if I play any video content.

PS: attached a dmesg log.

  • Reboot speaker, first bluetooth connect log
