2-in-1 Dell Laptop Volume Not Adjusting

Feb 25, 2018
I've got a brand new Dell Inspiron 15 7000 Series 2-in-1. The overall volume level will not adjust. I can press the keyboard buttons and it will show the volume level moving, but the volume itself doesn't increase or decrease. Same if I move the Speaker slider on the volume tab. If I open the volume mixer, I can adjust the sound of each individual program, but it seems a painful solution to something that should be working properly in the first place.

I have tried uninstalling and reinstalling my sound drives, both by just letting Windows replace it, and by redownloading and reinstalling. I have tried troubleshooting the sound with Windows. I'm not sure what else I could do to fix this. I like this laptop and I don't want to return it.
