High Measured Interrupt to Process Latency Problem

Postby scipio » 2018-10-14 13:06

Hi guys,

I have some issues such as suttering/popping noises. This issue occurs in both Windows 10 and Debian 9.5. I used LatencyMon in Windows and it seems that the most important problem is "Highest Measured Interrupt to Process Latency". I have searched on google about the problem and seen that it's mostly related to the audio, video or pci communications drivers. Though I couldn't reach a solution in Windows and don't know how to meddle with drivers in Debian. So I am waiting for your help.

UPDATE: In Windows, I totally disabled Intel graphics and switched to Nvidia. The problem is totally gone. So, I have uninstalled the Intel driver and installed the latest one. The problem is mostly solved, occurs less than before. So, it looks like a software problem but having the same issue in Linux doesn't make sense.

This is inxi -Fx output if it's helpful;
