I just picked up a DIY edition with the AX210 module (no vPro). It seemed at first like it all “just worked” on Fedora 35, but I’ve found that when I use my Bluetooth headphones, they will frequently disconnect. But not in the way I’m used to. The laptop basically just stops sending audio to it, and shows it as disconnected, but my headphones don’t seem to “notice” for a minute, and once they finally do (I hear the beep boop that it uses to tell me that) it seems to quickly reconnect (boop beep) and then audio streaming resumes.
A few relevant package versions:
- Linux kernel: 5.16.12-200.fc35.x86_64
- bluez-5.63-1.fc35.x86_64
- gnome-bluetooth-3.34.5-2.fc35.x86_64
journalctl output around this happening is a bit noisy, but likely the most relevant messages:
logs
When I fire up the bluetooth settings and connect my headphones:

then, a lot of messages like this:
Mar 09 21:49:05 framework-lappy bluetoothd[922]: src/adv_monitor.c:btd_adv_monitor_offload_supported() Manager is NULL, get offload support failed
And then, around when the sound stops:

Mar 09 21:49:34 framework-lappy wireplumber[2206]: 0x55e46ade0168: ioctl fail: Bad file descriptor

Mar 09 21:49:34 framework-lappy gsd-media-keys[2339]: Unable to get default sink
And this this starts repeating periodically (along with the Manager is NULL error above):
Mar 09 21:49:40 framework-lappy bluetoothd[922]: src/profile.c:record_cb() Unable to get Hands-Free Voice gateway SDP record: Host is down
Any advice would be greatly appreciated! These same headphones haven’t had issues like this working with my phone, macbook, windows desktop, etc, so it seems to be specific to either Fedora 35’s software, or the Framework hardware.
