[QUOTE="knutinh, post: 162206, member: 14776"] But do you prefer the audiophile gold plated stuff even if it gets you worse A/V quality? Using the PC hardware model, there is no way (AFAIK) to synchronise the audio and video card clocks. Whats worse, the cards are pulling data from system at their pace. As all man-made clocks drift, the a/v graph has three options: 1. Do nothing, let each media card receive data at its pace, and observe lip-sync issues into the movie. 2. Drop/replicate video frames whenever audio sync drifts far enough from video sync (this is what WMP does I believe) 3. Resample audio so that the video clock is essentially master, and audio is massaged to slave to that. This will distort audio, especially if you are working on DD streams. I would prefer one or two HDMI connectors with 8 channels of 24bit/96kHz audio, running in sync with the video. Then my surround receiver is reduced to a DAC-unit with amplifiers, just the way Id like it. -k [/QUOTE]
