SUMMARY
On openSUSE with PipeWire, when switching Bluetooth audio profiles in KDE (both
for PulseAudio and PipeWire), there is no sound output when selecting the LDAC
profile. This issue occurs consistently after switching between the mSBC and
other (specially LDAC) profiles.
Steps to reproduce:
Connect a Bluetooth device (e.g., headphones or speaker).
Select the LDAC profile and play media in Firefox (sound is output
correctly).
Switch to the mSBC profile (sound is still output correctly).
Switch back to the LDAC profile (video is playing, but there is no sound).
Switch to the mSBC profile again (sound is output correctly).
Switch back to the ACC profile (video is playing, but there is no sound).
Switch to the mSBC profile again (sound is output correctly).
Set the LDAC profile again (no sound). Disconnect the Bluetooth device,
reconnect, and select the LDAC profile (sound is output correctly).
If the profile is changed and then set back to LDAC or other profile that's
not mSBC, the issue persists: no sound output, and the following logs appear:

Additional notes:
The issue is observed with both PipeWire and PulseAudio backends in KDE.
Uninstalling PipeWire and using PulseAudio with KDE’s two available
profiles still results in no sound after switching to LDAC.
I am using wayland with KDE6 in case it makes a difference.
I am using Sony headphones.
