Hi

Help my sound has just stopped!coming from my speaker but works on headset jack, checked in device manager all ok and suppose to be working, its pulsing in the sound bar when playing music but no sound, downloaded and checked my hotkeys driver as i had recently added a backlit keyboard cant remember if it had sounds before i changed it as i usually use the headset any ideas

What OS?
Have you been using windows and linux?

[scotguy]

windows 7 32 bit

Where you testing Linux on it?
If so, You must boot Linux again and turn the sound on in Linux. Then shut it off and reboot windoze.
For some weird reason, If you mute the sound in one OS, the other can't turn it back on.

Otherwise, try uninstalling the driver and reinstalling it.
