Windows 10: Upgraded motherboard, now sound gets out of sync

Recently I upgraded by motherboard and CPU (and RAM), the old one being an ASRock Z68 Pro3, the new one being an ASUS Prime Z390-P.


Everything went surprisingly well and without any problems... except for one thing. I had been using this PC with the old motherboard for almost 10 years without any sort of video/audio problem, but after the upgrade I quite quickly noticed a very annoying problem: In pretty much all video players (including those that run on the web browser, such as the YouTube player and the Twitch player), the video/audio sync would slowly drift, until they are completely out of sync. When playing some video eg. with Media Player Classic, I measured them getting out of sync by approximately 1 second in 5 minutes of playing the video. However, this seems to depend on what's being played, and with what (for example with YouTube it's extremely inconsistent, with some videos not getting out of sync almost at all, while others get out of sync very quickly).


Curiously, and very strangely, shutting down the PC, which makes Windows go to hibernation, and then starting it up again (which makes Windows restore itself from hibernation) fixes the problem... mostly. In the vast majority of situations the drift is gone, and all video and audio do not drift apart anymore... except that there's still a barely noticeable but annoying difference in sync between them. With Media Player Classic I have measured, at least with some videos, it's about 70 ms. If I put an audio delay of that amount in MPC, then the video and the audio sync perfectly. By default, however, there's that barely-noticeable but still annoying delay. With eg. YouTube videos there's no recourse, as it has no audio/video delay option.


As mentioned, I had used this PC for almost 10 years before the motherboard upgrade, and never had any such problems. They started immediately with the upgrade.


I have tried completely uninstalling both video and audio drivers, and reinstalling them from scratch. It made absolutely no difference.


I'm wondering what the approach here should be. I'm wondering if resetting Windows from the system settings could perhaps fix this.


I must confess I'm not extremely eager to do that. I do understand that resetting Windows will keep all my data, but if I understand correctly, it will uninstall all third-party software, meaning that I will need to re-install everything from scratch, which will be quite an amount of work. And whether it will actually fix the problem is not guaranteed. (If I knew with 100% certainty that it would fix the problem, I would do it in a heartbeat, right at this very second. However, I dread doing so only to find out that it has done absolutely nothing to the problem, and now I have to reinstall every program, while still having the annoying audio sync problem, so the whole process was a completely useless waste of time.)

Sound Quality


One thing that sticks out from looking at your "My Computer" specs. You list "ONBOARD 6 CHANNEL (5.1) HIGH DEF AUDIO (AS STANDARD)" which suggests you do not have the correct sound hardware driver. Your motherboard has Realtek sound and the first step is to install the Realtek sound drivers. My ASUS also came with Sonic Studio 2 which is a sound enhancement package. Check the ASUS install disc to see if you have something similar.

May not be a speaker problem.

 

Good surround sound headset

I know you say you're not that guy, but stepping into the $250+ range really brings a change in build quality that might have you never having to buy another set. Otherwise, getting 6 speakers with decent sound in a headset is hard, and that's what you are asking for, and I have no suggestions, but just a bump up the list. *Stick Out Tongue
