Problem with Audio Driver

Good morning.

I made the mistake of moving to Windows 11, but when i have problems I wanted to go back to Windows 10, so I formatted everything and reinstalled Windows 10, but I did not take into account that it had to be installed with a special “ISO” for the Chuwi Hi10X.

Now, I have a problem with the audio, I installed the driver pack (that I got from this forum) that are not installable to reinstall the audio drivers, but they do not install. That is, if I try to install them it is as if I have done nothing.

I have even tried updating and uninstalling the supposed multimedia audio driver, but it keeps telling me it can’t find any and keeps saying there is no multimedia driver.

Thank you very much in advance.
Best regards.
