I have a Sony VAIO VGN-FZ31M laptop.
When I started it one day the sound was no longer working.
I have checked all diagnostics etc, and there are no errors reported, instead says sound is working. Windows Media Player is the only software that reports that sound can't be played due to problems with the audio unit.
Is there any way I can check if there are problems with the audio drivers, or if the problem is the audio card?
