Hi all,
My laptop has gone mute and does nt play any sounds.
Youtube is crashing and WIndows media player says " ERROR"
When i open the control panel to test audio it shows as " application is being used by other program" ?
.
Is this a driver issue or anything related to hardware.
pls help ASAP
.
Thanks

Do one thing: go to the device manager, uninstall the sound card. Right click and select scan for hardware changes, then the device should install properly. If it doesn't, the drivers are probably fired. If it does and still the issue persists, it *may* be a hardware trouble. I'm not sure about this though, just a guess.
