A puzzle.
Actually, what you're describing does not sound at all like what I'm suggesting is happening here. To be clear, I am not talking about "losing sync" as in the s/pdif receiver is not getting a valid stream. I am talking about data being clocked at the wrong rate into the dac, causing bit errors in the PCM data. The reason I am suggesting that is because the specific mods that Jitterbug made to his hardware would be _expected_ to behave like that if the sync connection were not working. It's basically the same as if you had a DAC in word clock mode, but the source component was in regular (master) mode. You get two different clocks. However they will be close enough in frequency that most of the data gets through, but you get some occasional cracking. Now, maybe this has nothing at all to do with that, in which case it may in fact be the same problem that you experienced. The fact that this happens only at track transitions is (at first glance) INconsistent with the clock-out-of-sync explanation. That's why I'm not entirely confident that's what's happening. The thing is, there is nothing special that happens on our s/pdif output at a track transition. It just pumps data all the time and simply has no notion of tracks changing. -- seanadams ------------------------------------------------------------------------ seanadams's Profile: http://forums.slimdevices.com/member.php?userid=3 View this thread: http://forums.slimdevices.com/showthread.php?t=37264 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/audiophiles
