Hello Johannes~,
Welcome to the Microsoft Community!
I am very sorry to hear about this problem you have encountered, it seems to be a rather tricky problem. First of all, I would like to encourage you that the measures you have already taken are very correct, you have turned off audio enhancement and spatial sound effects, as well as making sure that all drivers are up to date. These measures usually solve most audio problems.
From your description, I can see that the problem you are experiencing is a random shift in audio balance. This can be due to a number of factors. I've noticed that I don't encounter this problem when plugging in headphones, it only happens with laptop speakers,
- In this case, reinstalling the driver does not solve the problem, then you can try to use the troubleshooting tool that comes with Windows 11 to resolve the problem. You can find this tool in "Settings" and it can help you diagnose and resolve various audio issues. The steps are as follows:
- Windows Search and Open Settings -- System -- Troubleshooting -- Other Troubleshooting -- Click the Run button after playing the audio at ----, wait a while for it to complete, and test if this issue can be resolved.
- You can try to create a new account to test whether random deviation of audio balance still occurs after login. If the same problem does not occur, it indicates that the configuration file of your user account is faulty.
For details about how to Create an account, see "Create a new Local Administrator user account" in the following link.
If you need to restore the account configuration file, See the "Copy files to the new user profile" section in the linked document.

- This may happen if some third-party application changes some Settings or affects system files
I recommend trying a clean boot which starts Windows with a minimal set of drivers and startup programs. It can be used to determine whether a background service or program is interfering or causing a problem.
For detailed steps, see this document link:
Fix a corrupted user profile in Windows - Microsoft Support
These steps of "clean boot" might look complicated at first glance. However, to avoid any trouble for you, please follow them in order and step-by-step.
- Use the system file checker
You may consider using the System File Checker tool to repair lost or damaged system files, as detailed in the following links:

- After completing the above scheme, you should be able to find the root of the problem, if the above scheme can not fix the situation, I recommend you to try the operation of non-destructive repair:
A non-destructive repair is performed using an iso image file for repair and upgrade, and using a Windows 11 ISO file for repair. Performing the iso file repair operation will not affect your files, but it is recommended that you back up important files just in case. For details, please refer to the following document links:
How to: Perform a Repair Upgrade Using the Windows 11 or Windows 10 - Microsoft Community
After a non-destructive repair, if your media creation is normal, then you should not experience this problem again, if your situation is still continuing, it indicates that there is a problem with your hardware, it is recommended that you contact the manufacturer's technical support department or take your laptop to the local repair center. They will be able to provide more in-depth diagnostics and solutions.
You are welcome to share the progress of this issue with me, and please feel free to reply if you have any other questions on this issue. Thank you for your patience and cooperation, I wish you all the best!
