Hi,

I have a Dell Latitude 5420 and recently purchased an external sound card. However, I've been experiencing issues where the audio signal cracks, drops, and glitches at times. After running LatencyMon to check the DPC latency, I discovered that the latency is very high.

I've tried various solutions, but the issue persists. I suspect it might be related to the Dell laptop, as I don't encounter this problem when using the same sound card on my Mac or my son's PC.

Can someone please give me a hint how to eventually solve that?
