Everytime, I have been able to relate that to the known bug in MacOS related to "kernel[0]: IOAudioStream[0x4d83000]::clipIfNecessary() - Error: attempting to clip to a position more than one buffer ahead of last clip position (d24,39)->(d57,3b5)"
This is frustrating because the problem belongs to Apple but they ignored it for years (it is known to appear on some USB interfaces as well as firewire) and therefore, unless Apple corrects it which is unlikely, the only solution for Devialet is to work around it.
Is this a software bug or timing error?
It depends on how the clocks are handled but if they are not locked, and differ in frequency, they may eventually get more than one buffer out of step after a certain time. I would then expect this sort of error message.
The length of time between starting to stream music and the first hesitation would then depend on the difference between the actual computer and Devialet clocks involved, and if they were almost the same maybe one would not get a dropout in any realistic length of listening session. If they differ more maybe there will be a dropout in every session, and even more frequent with HR files.
