Audio Dropouts with ASIO S11

Hello

I am using Rekordbox on my computer without any dropouts. On my laptops (Huawei and Lenovo X1 both with 7th/8th gen i7 CPU) the audio dropout meter is between 60 and 100%, even no sound is playing.

I have increased the buffer to 15ms which reduces dropouts but not completely. Much higher values will make latency too extreme.

When switching to the local soundcard, I have no dropouts and the dropout level is around 20%.

level without playing any sound. WIFI disabled and ASIO, 13ms:

While selecting a no ASIO driver, the level is much lower, no dropouts at all.

Bios on both laptops are up to date.

Any hints to this?

Thanks a lot for your help
