[SOLVED] Windows 8.1 Sound "crackling" maybe high DPC latency

[Greby]

Hello,

first english is not my native language, so please forgive my bad english, i'm doing my best.

I just got a new pc and from the beginning the sound was crackling. I did a lot of research and found the DPC latency issues and used the LatencyMonitor tool to find out wheather this might be the case here.
the Tool shows me 2 drivers with more than 30 ms execution time. This two are storahci.sys and CLASSPNP.sys. everything else is below 1 ms so i think this two drivers might be the cause of the problem.
Refering to the driver reference table they are both Windows update related and i can't find anything to do about the issue.
Is there anything i can do to solve this?

Thanks everybody for reading

You should try the following. The Power plan set to high perfomance, as this will reduce DPC latency. DPC latency may be the cause of why it occurs crackling sound.
