[QUOTE="CyberSimian, post: 1152236, member: 141969"] For several years I used the analogue output from my HTPC to a stereo analogue amplifier. The strange behaviour that I noticed was this: [i]The analogue output from the motherboard socket at the rear of the PC was much noisier than the analogue output from the headphone socket at the front of the PC.[/i] :eek: From looking inside the case, the headphone socket uses a cable that connects the socket to the motherboard, and which snakes through the case between other components. I would have expected the cable to be susceptible to interference from within the case, and hence be worse than the motherboard socket at the rear, but the reverse was the case. :confused: My current setup uses HDMI audio to the TV, and then analogue audio from the TV to the amplifier. -- from CyberSimian in the UK [/QUOTE]
