Right after approx. 5 months!!!!! My sound works!!!! It
might not work for every one but worth a try. I tried
everything and l mean everything....................now l
got my sound back full belt, check your volume by the
speaker in task bar, yes ive done it a thousand times
too!!!

just do it! Next do you have a mic??? REMOVE
IT!! unplug your speakers from back of tower are you
getting really loud buzzing type noise??? Right now leave
the mic out and try the speaker plug in different
holes........... it should work!!! I am over the moon
mines sorted, l believe some of us downloaded updates and
this had something to do with it,maybe through mic....my
mic is labtec.........anyone elses whose lost sound or
sounds been very low? l have not tried the mic back
in.........Im too happy lve got me sound back to try just
let

Good luck
