kernel: Bluetooth: hci0: corrupted SCO packet

[DittelHome]

Hello community,
I'm trying to get my Bluetooth headset "New Bee LC-B45" up and running. Pairing worked perfectly. Sound playback worked too. According to the Sound Manager, the microphone only works if I select "Headset Head Unit (HSP/HFP Codec CVSD)" as the audio profile. Then the input level is at least displayed. A recording with "arecord --duration=5 test.wav" is disappointing, all you hear is scratching.

During the tests, I get hundred's of this error messages:
kernel: Bluetooth: hci0: corrupted SCO packet

I use:
Distro: Linux Mint 22 Wilma base: Ubuntu 24.04 noble
Kernel: 6.8.0-47-generic
Bluetooth: Intel Bluetooth wireless interface driver: btusb v: 0.8 type: USB rev: 2.0
Laptop System: LENOVO product: 80KX v: Lenovo E31-70
Fresh install of mint

Where can I address the problem?
or
What can i do, to fix the problem ..?

regards Klaus

To create an issue I have to assign the problem to a repository. But I can't find anything regarding the kernel.
Blueman is only the Bluetooth Manager.
Where can I address the problem ?
Sorry for my stupid questions.
