X250 Sound via audio-jack with Catalina

I have very strange behavior on my X250, and till now, I have no solutions for it. Maybe someone has experienced the same and knows how to fix it?

In battery mode:

- Function only given after restart, and then for about 15 minutes, until the sound breaks up via the jack, with loud noise

- Sent to sleep mode and woken up - no function directly, but noise.

In loading mode:

- Function given at restart, and then continuously, without noise.

- Sent to sleep mode several times and woken up again, sound clean, not the slightest noise.

If it works for you, maybe you can tell me something about your BIOS settings?

Thanks in advance!
