HP Z1 High DPC Latency - sound is stuttering

Z1
Microsoft Windows 10 (64-bit)

Hi every one.

Z1, after last updating of Win 10 to ( 1809 - how I understand)   - sound while playing pf video or music begin to stuttering.

 

I can not watch any video (inc You Tube), listen to music and so on! 

 

- I reinstalled (the newest) Nvidia drivers

- run the Windows Update Troubleshooter

- install an updated audio driver (de instal in device manager and  turn on) 

 

- Re install windows  - but it was not result  

 

After it I find out that is with DPC Latency Cheker that is the problem
