When I have my volume at 2 or 100 the sound is if it’s at 100 no matter what. The only way I can change the volume is by going into the volume mixer and switching the settings around there. So right now I have Firefox at 10 in there to have it at 10 volume, but if I want to raise it I can’t use my volume button I have to keep going into my volume mixer settings. This is Windows 11 Speaker (Realtek ® Audio).
The volume button works if I lower it all the way. Anything 1 or above is tied to whatever value I have the app set at it the volume mixer. And even then the volume is still much louder than usual.
