on my two notebooks, one with Ubuntu (Mainline Kernel 6.9.3, bluez 5.7.2) and the other one with Manjaro (6.9.3, bluez 5.7.6) I'm having problems with my Sony WH-1000XM3 and Shure BT1. Either A2DP or HFP/HSP is not available after the connection has been established after a reboot or a reconnection. It's reproducible that with the WH-1000XM3 the A2DP profiles are missing and with the Shure BT1 HFP/HSP profiles are missing. It also takes longer than usual to connect and I have a log message in the journal: Jun 06 16:28:10 liebig bluetoothd[854]: profiles/audio/avdtp.c:cancel_request() Discover: Connection timed out (110) When I disable and re-enable bluetooth (while the Headsets are still on) and trigger a reconnect from the notebooks, A2DP and HFP/HSP Profiles are available again. I also tested it with 6.8.12 and it's the same problem. 6.8.11 and 6.9.2 don't have the problem. So I did a bisection. After reverting commit af1d425b6dc67cd67809f835dd7afb6be4d43e03 "Bluetooth: HCI: Remove HCI_AMP support" for 6.9.3 it's working again without problems.
Thank you for bisecting the issue.
Let me know if you need anything from me.
If you could test the master branch or bluetooth-next, and, if reproducible, also with the upstream commit 84a4bb6548a29326564f0e659fb8064503ecc1c7 reverted, that’d be great.
Kind regards, Paul
