Hi I'm having a real problem with my new Home Cinema PC. It is connected to my Yamaha DSP A2 via digital coax or optical. Problem is the sound cuts out for between 1 sec and 3 sec totally randomly whilst watching a movie. I have taken the PC back to the dealer who supplied the parts and he has kindly hooked it up to his Denon amp and has reported back that no problems were found. This makes me wonder if some amps are more susceptible to SPDIF feeds than others. I have swapped interconnects and this has made no difference, also both my stand-alone DVD players work fine and the PC has all the latest drivers installed. Any advice would be welcome. Thanks.
