Audio distortion after Windows login; perfect before

Suddendly, my laptop is having distotred audio. Before the windows login screen the audio is perfect but afterwards the audio is horrible.

Hi @j0k3R185, welcome to forum.

Maybe third-party startup service or program causing the problem.

In this guide, you will learn the steps to perform a clean boot on Windows 11 and Windows 10 to help you troubleshoot and determine conflicts in your setup.

Second thread today about distorted sound, albeit the other one is after a clean install. You might take a look at the other one to see if you can get any ideas. Make sure WU hasn't updated your audio drivers. Certain system sounds are deep and distorted

As promised to report on my finding about this issue (see my thread above), my suggestion is to regularly check for Windows updates and hope MS releases a fix soon.
I did a thorough testing with fresh installed system and can with certainty say it's not driver issue but rather an issue with the OS itself, specifically 23H2.

Please run winver.exe from start menu and take a screenshot and share it here to confirm you have 23H2 installed.
