Is it possible to restore volume settings after update drivers? #58

Open nkh0472 opened 3 years ago

nkh0472 commented 3 years ago

Every time I use this script to update the driver, the system volume is reset to the default 67% (approximately). And then some warning tone will scare me to death (I usually set the volume at 1~6%). So is it possible to restore volume settings after update drivers?

You can try disabling speakers in Sound settings - Manage sound devices before update and re-enable them after update completes. I don't know of a way to preserve volume settings on update unless you want to get your hands dirty and update manually using device manager and force updater only.

First of all, I used the directory monitoring software to monitor the changes of files in the root directory and subdirectory of windows when the volume was changed. The conclusion is that the volume is not obviously saved to a file, but the registry has access records. After that, I adjusted the volume, grabbed the registry dump four times and compared them. The conclusion is that the common key values of registry changes are as follows:

It doesn't seem to show any regularity.

After that, I found that windows provided the corresponding API: IAudioEndpointVolume::GetMasterVolumeLevelScalar method IAudioEndpointVolume::SetMasterVolumeLevel

I thought that PowerShell should be able to call these APIs, so I Googled "PowerShell set windows volume" and found this: Change audio level from powershell? There are many PowerShell scripts that can get the current volume and set the volume. I think that simply pasting it into this project may work.

I'm not very familiar with windows scripting, but I think these can help you.
