How do you know if a reinstall won't work if you haven't tried it ?
You do not read with understanding. I had to install the system from scratch, because the clean WMP installation is on the DVD. But that does not change anything.
Audio device control The problem does not occurI'm not a layman and I know dozens of different solutions
Method 1.
Try using the troubleshooter to see if that fixes the problem.
a. Open the Windows Media Player Settings troubleshooter by clicking the Start button, and then clicking Control Panel.
b. In the search box, type "troubleshooter", and then click Troubleshooting.
c. Click View all, and then click Windows Media Player Settings.
Method 2.
A clean boot helps to verify if any third party application service or startup item is causing this issue.

Note: After you have finished troubleshooting, follow step 3 in the article to boot to normal startup.
Method 3.
You may update the video card driver and check.

Method 4.
I would suggest you to perform SFC scan and check if that helps. The SFC /scannow command scans all protected system files and replaces incorrect versions with correct Microsoft versions.

Hope this helps.
, but it does not change anything. I know so many solutions, but this one is unique in this case and I do not know where to look for a solution.
I understand that you do not want to help. Because what you propose does not solve the problem.
I do not want you to suggest solutions that I know perfectly well because it will never solve the problem.
I do not know the problem, but I am looking for a solution, maybe the process related to WMP is "
stuck" or "
DeadLock" - if you do not know what it means, I refer to google.
