When I mute the volume, the volume will not unmute when using the hardware keyboard volume keys until I manually unmute (regardless of whether I raise or lower the volume). The volume is raised (or lowered) as much as was done with the keys while muted, when unmuted. It has been that way for at least the last 4 builds for me.
As I said, the volume goes up or down by keypress when muted, but neither keypress causes the volume to unmute. When unmuted manually, the volume is at the level that was selected by keypress when the volume was muted. Is that clearer ?
No, mine stays mute whether I press down OR up and has done so for at least the last 4 released builds. I don't know how to make it any clearer!
When it mute you must press down first because if you press up first and then down the volume will unmute. The feature start in this build.
Ok, I understand what you mean now. You're talking about using the mute in volume control on the taskbar. If I do it that way, then yes, it unmutes with those keypresses. But my Logitech keyboard has a volume+, volume-, and a mute key. If/when I use the mute key on the keyboard to mute the volume, it doesn't matter in what order I press, it does not unmute. It does change the volume level, but does not unmute. Then I must use the mute key to unmute (or unmute with the volume control in the taskbar). It has been that way for at least the last 4 builds. Prior to that changing the volume with keyboard presses, always unmuted.
My Lenovo Thinkpad has an issue with the hardware keyboard mute button as well. I have a button that mutes the audio, and it has a red LED that lights up when the audio is muted. If Windows starts, and the audio is muted, the LED does not light up. If I press the button, it works properly, in that it toggles the mute, and the light toggles as well. But that means that now, the light is ON when the sound is ON, instead of being ON when the sound is OFF. To fix this, if Windows boots with the audio muted, I can use the hardware volume down button to turn the volume UP, and then the volume is unmuted, and the light stays in the OFF state. Then, the hardware volume button works properly, in that when the LED is ON, the volume is OFF. I think there's probably not a way for Windows to ask the keyboard if the LED is on or off, and the light can't be toggled unless the button is pressed (I don't believe, anyway, because if I mute the volume with the button in the taskbar, the light doesn't come on). So I'm not sure there is any way to fix this.
