I want to be able to play the music I have on my laptop, and have the sound come out of my hifi. I bought these connecting cables http://www.amazon.co.uk/exec/obidos/ASIN/B00006JD8W/026-8509635-3834027?_encoding=UTF8 it came today but this isnt working...ive connected it from the headphone jack on my laptop to the TAPE (MD) two slot inputs at the back of my hifi, the only spaces there are to connect something into, and i got that channel selected so MD comes up on the screen. so everything is connected up right to my hifi, i got music on my laptop playing, but when i put the plug in the headphone jack on my laptop, SILENCE! i phoned up hama and the dude said that the signal from the headphone jack isnt powerful enough...? he said i buy some kind of adapter but he couldnt find it. i spent nearly £12 on these cables! VAT! are the cables i got not enough/the wrong ones? what do i need? i would appreciate any help i could get because i have no idea. oohhh and at the back of my hifi theres a "CD OPTICAL OUT (DIGITAL)" since socket, which is like a black plastic flap, which doesnt look like a normal plug would go into!?
