[BUG] Buds2Pro don't appear as audio device after restart on Linux

[amenaijp]

Describe the bug
After restarting host laptop, my buds2pro don't appear as an audio device on KDE Plasma. The buds appear in the bluetooth devices menu, and GalaxyBudsClient can read data such as battery info. After forgetting the device and repairing, they work as expected, and can be put away and taken out again, and they will continue to work as expected. They also continue to work after host sleep/wake.

To Reproduce

1. restart host device with the buds2pro already paired from a previous session
2. open GalaxyBudsClient
3. open buds case
4. try and connect from GalaxyBudsClient
5. After a while, expected battery info etc shows in GalaxyBudsClient; buds however don't appear in the Audio Volume menu and aren't listed as an audio device

bonus:

1. Open bluetooth system settings menu
2. forget earbuds
3. open buds2pro case, set them to pairing mode
4. open "Add New Device..." and pair normally
5. should work as expected now, even after putting buds away and opening again

Expected behavior
After restart buds should be working normally after connecting to them, listed as an audio device etc
Shouldn't have to forget and repair them

Desktop (please complete the following information):

• KDE neon 6.1 x86_64 (Ubuntu 22.04 base) (edit: updated to neon/plasma 6.2, Ubuntu 24.04, still persists)
• Kernel: 6.8.0-45-generic
• KDE Plasma 6.1.5 (persists in 6.2)
• Application version (from ./GalaxyBudsClientExecutable --version): GalaxyBudsClient 5.1.0.0+a45b7b62808734f95c9c6f38d3027bf768d79cee

Additional context
bluez version (from bluetoothd --version): 5.64 (persists in 5.72)
can send dump.bins of the bluetooth exchanges if you want (is there anything sensitive stored in the dumps)
might be a bluez issue? but since the buds seem to have a lot of proprietary stuff going on anyways i wanted to check here first

Log files
Killed the app after both tests, IME errors probably aren't related

I have this regardless of the Buds2Pro app. I don't have it installed right now and I also need to pair my buds after every single reboot. Subscribing in case anyone has a solution.
