DxDiag Notes
------------
Sound Tab 1: The file RTKVHD64.sys is not digitally signed, which means that it has not been tested by Microsoft's Windows Hardware Quality Labs (WHQL). You may be able to get a WHQL logo'd driver from the hardware manufacturer.
This driver is from 2013. Please check with RealTek for a newer supported driver.

All the best!

I just opened a random dxdiag from another customer and they have:
Driver Name: RTKVHD64.sys
Driver Version: 6.00.0001.8242 (English)
Date and Size: 01.09.2017 00:00:00, 5911528 bytes
So there are certainly updates available! I've never trusted that Windows driver update utility, it always seems to say that.

You may need to contact RealTek if you can't work out how to get updates from their site.

Good luck!

I am sorry their site is so bad, I had no idea! I don't really know what else to suggest, if you cannot get in contact with any actual support there.

Clearly people are getting newer drivers from somewhere!

What if you redirect sound to be via the nVidia audio driver you have there?

I was unable to duplicate this problem. By 'closing' do you mean X-ing away the list of tracks?

This problem aside does it appear to work okay?

Has this always happened ever since you've had the game? Or only since what change or update?

Fixtheerrors said: It's actually done it for a long time now on three different PC's.
Really!?! That does surprise me, I was going to get you to do a clean reinstall but it seems like that wouldn't help.

What do these PCs have in common that it seems no one else has or uses? Do you still have access to the other two?
