Hi, firstly let me preface this with a) I'm not seeking the holy grail of home cinema, just functional, and b) I'm an idiot/novice, depending on your personal opinion. I brought a Sony KDL-32V4000 tv, and a new laptop, an Asus X59SL-AP338C. I've got a HDMI / DVI cable, and ta-da I can see the laptop screen on the tv screen (setting HDMI 3). So far, so good. Now the sound part... I've got 3.5mm Jack to 2 x RCA Phono Audio Cable Gold 5m Lead. I plugged the jack into the laptop's headphone, and the two RCAs into the back of the tv, into the points marked 'Hi Fi Audio Equipment', given that they were the same colours as the RCA knobs. No sound, so not so good. Next attempt was to plug the RCAs into the points marked 'Mono L & R'. Still no sound. Things I have checked; all the other component knob holes pulling the jack out of the laptop to ensure there is actually sound testing headphones in the jackpoint so I know sound broadcasts out of the jackpoint The boyfriend's suggestion is we give up, and buy some computer speakers to put beside the tv, but it makes a mockery of the whole set up. I know I'm quite probably doing something stupidly wrong, but if someone has the patience to help me using words of two syllables (as I know nothing about this stuff), I'd be grateful.
