Changing volume on Bluetooth headset causes applications to crash.

Hello! So I'm not 100% sure if I stumbled onto a kernel bug or if this maybe PulseAudio doing. I've heard some say PulseAudio's bluetooth implementation is buggy. It works enough I can get by with some of it's weirdness up until now. If this is truly PulseAudio...

How I can re-create it.
- Startup machine and wait for bluetooth to connect.
- Change volume up/down on bluetooth headset.
- All applications crash. i3 or services in the background don't seem to be affected.
- I can now up/down volume without issue. <shrug>
- Reboot machine and same thing happens all over.

journalctl -f:

For the record I'm using TP-Link USB Bluetooth Adapter for bluetooth since my motherboard doesn't have on-board bluetooth. I tried Googling around for people with the same issue, but I haven't found much.

My uname -a:

Linux mah-desktop 6.1.34-1-lts #1 SMP PREEMPT_DYNAMIC Wed, 14 Jun 2023 17:36:07 +0000 x86_64 GNU/Linux

Re: Changing volume on Bluetooth headset causes applications to crash.

https://wiki.archlinux.org/title/Core_d … _core_dump
teams will probably not provide the best possible backtrace, if sth. w/ https://wiki.archlinux.org/title/Debugg … g_packages crashes that's gonna be very helpful.
