i did find this- don’t know if it works or not- but worth a try i guess (Im on linux so i can do it)
“- Press the Windows key + I simultaneously. - Click on Settings. - Next, find Ease of Access from the list and click on it. - Select Audio on the left-hand bottom corner. - In the middle of the screen, you will find the Make your device easier to hear option. Use the slider just below it to increase the volume. - Close the Settings menu.”
