Have no sound, on vista premium, had this problem when bought it three months ago but it was because jack lead was missing, bought one and got sound but last sunday it went, have checked for drivers and its up todate, went into device manager from help and sound card is ok and somewhere l did a test for sound and it was low but sound on nrealtek high defintion audio left side but all speakers are muted so thats were l need to know were the mute button is. Checked all over the web and its a round button well l have not got one, my keyboard is a plain one but bought new last year, its one for if spilling drinks it goes throught it. So which will be my mute button ,speakers are built in to the moniter at botton right and left side Jade
jack lead is ok and others, checked back of pc as well and its not the same as xp, wish it was. When right click it comes up with two devices for a better word, one it says windows and other is device and both sound is up high but mute and when the speaker icon is clicked the red circle comes on. When l went into device manager from trouble shooting there is a button to check sound and it was low but there was sound but from there on am lost and have been round the web as didn't want to bother you again. When l saw about mute button on web, hoped it was that as got a new pc table and had sound before it was put in then none so thought something could have got knocked, Jade
