Although I have posted this elsewhere, here is a little information from Devialet about 2.1.4 beta4:
... the problem is not in our software (PC or firmware 7.x) but deep into the windows operating system, though the workaround is in AIR.
The issue for PC users was we were using a timer to schedule the pace at which the audio samples are extracted from the audio driver, and under some specific circumstances, for instance some part of windows entering low power mode, the timer exhibited quite important jitter -which should have been ok due to the size of the audio buffer- but in fact messed up the windows audio driver at the kernel level, generating randomly a one byte offset internally in the buffer manager. It was not memory garbage, unallocated buffer nor a programming fault on our side, it is truly a bug inside windows’ implementation, which obviously is not documented.
The workaround consists of using the most precise possible timer available on PC platform (which is more costly to the CPU load point of view) ... and we are currently testing the fix with several users ...
