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

You have been subscribed to a public bug:

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?
