It can't possibly have anything to do with "power line conditions" since the power input to the Squeezebox is DC, not AC. "Power line conditions" impacting time sync is -- and I do know a little bit about this, since one thing I used to do for a living was design digital carrier circuits for a telco -- something that went the way of the dinosaur with the General Electric 60Hz electromechanical alarm clock many of us had by our bedsides as kids. ;-)
I'm more than a little surprised that the units can't keep tight sync over the course of a song. They have an accurate oscillator of more than sufficient frequency available to drive the digital output -- if they didn't, it would have fierce bit sync problems, bad enough to be audible as glitches. Perhaps the digital output IC they use doesn't expose this clock to the rest of the system, or perhaps the rest of the hardware design doesn't allow its use to keep frames in sync during playback. Temperature variations would make sense except that my two units are in adjacent rooms. Basically, I have to ask "just how crappy are the system clocks on these devices, anyway?" since you'd need a *really* bad oscillator to slip by half a second over the course of a few minutes, which is what I'm seeing. -- tls ------------------------------------------------------------------------ tls's Profile: http://forums.slimdevices.com/member.php?userid=3411 View this thread: http://forums.slimdevices.com/showthread.php?t=24380 _______________________________________________ discuss mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/discuss
