My sound button wont go off mute/red. What is wrong with it?

If you have a hardware mute button on the keyboard, try pressing that. They usually look like a speaker with either an x beside it or a speaker that has a circle with a slash beside it. It may even be colored red.
The following answer assumes you're using XP, Vista, or Win 7.

If there is no mute button, click the speaker icon on the toolbar and see if the 'mute' box is checked. If it isn't, also use your mouse or touchpad to work the slider on the screen to try and turn up the volume.

Lastly, some Toshiba laptops have a separate hardware volume control on the front, like you'd find on portable radios.

if the little x over the volume bar is still stuck after moving it up you may have to hit the function key (fn) on your laptop and hit one of the F1-F12 KEYS that look like a mute or volume symbol also there should be a mute button on the laptop itself. if all that fails. go to (xp) right click on my computer -device manager-and see if you have a red or yellow x over your sound sound devices (win vista or 7) go to computer, sys prop on the top then device manager. if you see any of htose yellow or red warnings you will need to re-download the audio drivers from acer website Let me know if this helped.
