https://bugzilla.suse.com/show_bug.cgi?id=1226823 Bug ID: 1226823 Summary: bluetooth earphones fail Classification: openSUSE Product: openSUSE Tumbleweed Version: Current Hardware: x86-64 OS: openSUSE Tumbleweed Status: NEW Severity: Normal Priority: P5 - None Component: Kernel Assignee: kernel-bugs@opensuse.org Reporter: werwolf131313@gmail.com QA Contact: qa-bugs@suse.de Target Milestone: --- Found By: --- Blocker: --- I've been using Redmi Buds 4 Pro TWS headphones for several years now. everything was fine before. However, recently a problem has appeared: The headphones connect and work well if you listen to music in the player or browser, but if you make a call on telegram or discord, the system starts switching the audio output from the headphones to the speakers and back in an endless loop. in journalctl I see the following line:

I tried several usb bluetooth adapters on different chips, the behavior does not change when changing the adapter. Unfortunately, I could not understand the reasons for this behavior, so I hope for help. -- You are receiving this mail because: You are on the CC list for the bug.

You can try 6.7 and older from my OBS repos,
http://download.opensuse.org/repositories/home:/tiwai:/kernel:/6.7/standard/

Judging from your description, it's a problem that is rather new. If so, and if neither of the above kernels works, it would imply that it's no kernel regression but something else.
and so I found out something 1) changing the kernel to the one suggested did not help, the situation remains unchanged 2) when the A2DP+AAC profile is set, when trying to make an audio call, the profile tries to switch to HSP/HFP and cannot do this, but if the A2DP+LDAC profile is initially set, the profile switches to HSP/HFP without problems As far as I can understand, the issue here is definitely not in the kernel, but I don’t understand what target to choose for this bug report if not the kernel, I would be grateful for a hint. -- You are receiving this mail because: You are on the CC list for the bug.

OK. I just worried from the messages like

I'm a little confused that inxi does not show the connected headphones even when they work normally. but as they explained to me, this is normal for BT. Also you can see that pipewire

I tried it a few more times today. Still, sometimes changing the profile helps and sometimes it doesn’t, I can’t find a pattern. -- You are receiving this mail because: You are on the CC list for the bug.
