[Bug 2092655] Re: Audio dropouts with bluetooth earbuds for 3-5 seconds every few minutes

How do you prevent the machine from using 2.4GHz? It seems that they
removed that selector from the plasma nm client.

Title:
Audio dropouts with bluetooth earbuds for 3-5 seconds every few
minutes

Status in linux package in Ubuntu:
New

Bug description:
I am using Ubuntu 24.10 and I get a bluetooth audio dropout where the
desktop environment switches from my headphones to the speaker and
back to the headphones within the span of 5 seconds. This happens
quite frequently and even when audio is playing. The syslog shows:

2024-12-29T00:52:53.732631-08:00 iroh bluetoothd[60568]: profiles/audio/avdtp.c:cancel_request() Start: Connection timed out (110)

At the exact time that these dropouts happen. The same earbuds work
fine on android and on the steam deck so I think the problem is with
the laptop setup. Can anyone help?
