Sorry to shout but im having a real problem trying to get my HTPC to output to my Yamaha DSPA5 Amp. It only has Co axial and optical connections. i bought a phono to mini jack connector to connect from card to amp and have got absolutley ZILCH!!! Can the digital out be connected to an amp via a co axial cable . I have run all tests and am now at wits end!! Thanks to Fulabeer for the picture tips the image is superb now at 75HZ but a bit sad with no sound!!
