[linux-audio-user] spdif output clicking noises

Cross posted as this is a request for advice rather than a bug/issue report. When playing media using mplayer or xine, and outputting using ac3/dts passthru spdif, if I pause and resume playback, or seek, there are brief, horrible clicking noises when playback resumes, I assume this is because the stream is interrupted and resumes wherever it left off, so it outputs some garbage data that causes the noises. Is there any way to prevent this? Perhaps it is possible to make alsa dump the first 1/2 or even 1/4 second of audio that is played? That would avoid the noises and I could live with a slight delay when playback starts. Thanks Andy
