MSI GP62 6QF Leopard Pro Gaming Laptop Audio Distortion After Windows 10 Anniversary Update


Jan 5, 2017
Hello all, I seem to have an issue with loud and distorted sound on my laptop.

The laptop itself is less than a week old and the issue has only occurred since the Windows 10 Anniversary update, installed in the beginning of January.

Here is what I've tried so far:
- Uninstalling and Re-installed the Realtek audio driver via the device list. (both via the website manually and through the driver list)
- Using the default Windows audio driver.
- Checking all drivers for any updates whatsoever.

So the issue seems to not be limited to just applications, but any forms of media. The distortion comes in the form of raw, loud and unrefined noise. It is distinguishable, but very irritating to listen to.

MSI released a potential solution to this. Please click the link below:

Apparently, it could be to do with Nahimic, that was pre-installed on the computer.
