HP Spectre x360 - 15-bl112dx
Microsoft Windows 10 (64-bit)

I have been fighting with this laptop and am about ready to sell it and go back to Mac. When using my Universal Audio Apollo 8p interface, there are frequent clicks and pops that are audible during playback. LatencyMon application tells me that the main issue is ACPI.sys and occasionally also WDF01000.sys. They're each reporting Highest Execution times of up to 1.8ms.

 

Even when I have the laptop completely disconnected from anything, the DPC latency is very high, but no audible clicks or pops are heard.

 

I have tried:

-Updating all drivers both with Windows automatically and by clicking each and every driver and installing the SPs via the HP website.

-Completed all typical PC audio system optimizations including disabling system sounds, Processor scheduling for background services, Power options to High Performance, minimum processor state to 100%, don't suspend USB devices, disable background apps, removed many animation effects, turned off USB power management, disabled fast boot and hibernate.

 

Hopefully someone can help! Thank you.
