Dell XPS M1330 Speakers not working
Morning/evening!
Suddenly this morning the inbuilt speakers on my XPS M1330 Windows 7 installed(it came with vista) laptop stopped working
Problems
-Sound test in control panel gives 'Failed to play test tone'
-No sound in headphones/external speakers as well.
Have tried every damn thing:-
-re-installing sound driver from dell site (Drivers and Downloads) and (Drivers and Downloads)
-re-installing driver from dell resource cd.
-running install in compatibility mode, vista.
-BIOS Upgrade.
-Repair through windows cd.
-checking 'windows audio' services in the windows process
In the dell diagnostics test, I can hear sound in speaker as well as headphones.
And system restore doesn't have a recent restore point.
Please help help I don't want to do a format
Thanks
