Assuming everything were perfect in the data transport mechanism on the device, there could be variance from Squeezebox to Squeezebox due to the clock generation. Depending on the clock scheme, the audio decoder chip (the DAC) could have a PLL inside that might have some variance from chip to chip, so over the course of time, there could be drift. How much drift? I don't know, just a though. If the DAC doesn't have a PLL, then the master oscillator could be variance point. Typically the oscillators have pretty precisely specified frequency outputs, but with any system there is variance. Most systems that have synchronization characteristics use the same "system clock". This avoids clock gitter/phase issues.
If the data transport (music) was missing bits in the decode process, due to buffer underruns, data truncation, or something like this, the audio would get out of sync. If the bit errors were not catastrophic (hardly audible), but frequent enough, it's possible a delay could be noted. Basically, I don't know, but there could be reasons. I could look into the burr-brown data sheet to see if I can find anything that might be suspicious. -- verbatone ------------------------------------------------------------------------ verbatone's Profile: http://forums.slimdevices.com/member.php?userid=3556 View this thread: http://forums.slimdevices.com/showthread.php?t=24380 _______________________________________________ discuss mailing list discuss@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/discuss
