Hiya Unsure where this thread should live as it involves both Hi-fi & HTPC components... Have my HTPC hooked into my Pioneer 1014 amp via SPDIF output from the HTPC onboard soundcard. Whilst watching a DVD, the sound will cut for a split second every 5 minutes exactly whilst watching a DVD. Any ideas as to where the problem could lie? I've looked in the Amp manual and can't find anything about timing and can't see any relevant settings in Windows Media 2005 either in the system setup or the sound card options. Standard stereo through the amp is fine if playing Sky television etc., it just seems to be when using SPDIF output. I'm using PowerDVD V5 software that came as part of the WMC capture card. Any ideas? Cheers.
