XPS 9570 audio crackling/stuttering - DPC Latency

neutrino · Apr 13, 2020

Hello there,

I've had an audio issue with my XPS since I bought it. I had abandoned finding a solution until I recently decided to look again and stumbled upon this forum.
Everything I've been able to find so far points to a DPC latency issue but haven't found a solution.

I hope we can find a solution together.

Hi!

Please start by updating your BIOS to the latest version and temporarily uninstalling NordVPN.

I just did that. It did not seem to improve the audio issue.

Have you tried MSI mode on realtek audio?

Could you be more specific? I wasn't able to find any MSI mode in the Realtek audio properties.

I just checked the MSI mode. It was already set to 1. Would you suggest to turn it off (value of 0)?

Vezovi · Apr 15, 2020

You can try, but i don't think its gonna work. If it doesn't, switch back to 1.

I turned it off. It didn't yield any results. And then I turned it back on again. No changes in the situation.

I've tried uninstalling Kaspersky and Malwarebytes. That, however, didn't improve the situation.

Hi.

Try the following command from an elevated command prompt (also known as "command prompt ran as an administrator" or command prompt (admin)) and post its result here:

Code:

sfc /scannow

(It could last from 10 to 50 minutes, usually)
