No Sound from my Laptop

Damnnn......I have the HP Entertainment that I enoy watching Cricket

It has a built in speaket Altec Lansing SRS premiun sound.

I checked the Driver and there appear to be no problem.

First I downloaded that Free Iobit Driver booster :

Lemme try a restart ....Again !

Webcam / Skype says : No playback device

Youtube :an error occured and then there is snow on my screen.

Cricket stream : Video , NO voice commentary

Mute button is NOT on !

assuming you haven't made any major changes, do a system restore to a few days back
