-Hi, my name is Claudeir, I'm happy to help you!
In fact there is no specific setting for this as it is automatic, the volume should always go back to the level it was left on last time.
Does this same problem happen with speakers or headset that are not bluetooth?
Let's do a few steps, test if it resolved after each one:
-Right click on start, run PowerShell(admin) or Command Prompt(admin)
Copy and paste the following command:
DISM.exe /Online /Cleanup-image /Restorehealth
and press Enter.(Note: This step may take a few minutes to start and up to 30 minutes to complete).
After you see a message saying "The operation completed successfully", copy and paste this command:
sfc /scannow
and press Enter.
Wait for a message that says "Verification 100% complete".
So add this command:
chkdsk /f /r /b
Confirm with "Y" and restart the computer for this last step.
-Clean startup:
Clean boot is for you to determine if a background program is interfering with your system or to optimize your system load.
For clean boot follow the steps below:
On the Desktop, press the Windows + R keys simultaneously to open Run;
In the Run Menu type msconfig command and click OK to open System Configuration;
On the Services tab, check Hide All Microsoft Services and Click Disable All;
Click Apply and OK;
Restart the computer.
NOTE:This procedure disables all third-party services and programs. You can later, if the problem is solved in this way, enable the programs and services that will start with Windows, selectively, instead of keeping them all disabled. If the problem returns after activating the startup of a specific service or program, the problem is exactly in the startup of this software and it is recommended to remove it.
-Solve problems with bluetooth:
With the device connected, let's try troubleshooting:
Windows+i> Update and security> troubleshooting> additional troubleshooting> bluetooth> run solution.
See if it solves the problem.
If necessary, we will reinstall the bluetooth drivers:
Windows+X> device manager> bluetooth, right click on all drivers, Uninstall. Restart the PC.
-Let Windows reinstall all generic sound drivers:
Windows +X, Device Manager, under Sound Controllers, right click on all drivers, Uninstall. Under Audio Inputs and Outputs, right click on all Drivers, Uninstall. Restart the PC.
-Feel free to leave your opinion, marking as answered if the answer helped, or leaving more details so that we can continue the service, this is very important to us.
Graciously,
Claudei
