Comment 0 for bug 1845677

On my Lenovo ThinkPad X1 Carbon 7th generation using the built-in speakers, the volume is either off or on, there's no gradation in volume when I move the slider up or down.

If I enable Over-Amplification than there's gradation in volume when I turn the volume up past 100%, but not for 0-100%.

This problem does not occur with a headset plugged into the 3.5mm jack.
