This is a the second survey on AIR and the incidence of white noise. Please reply to it only if you replied to the first survey AND only if you ever got or get "white noise".
The results will be fed back to Devialet on an anonymised basis.
Please regard AIR as meaning AIR ethernet and/or AIR wifi, as the context refers.
This second survey seeks to break down the categories of white noise into:
EITHER a random repeating signal of fairly constant density, which might emerge quickly or after some time ;
OR dropouts ;
OR crackling.
I know some of these may just be network disturbances though these will generally be in the crackling or dropout categories.
Thank you.

Dropouts only. Not tested for long hours yet to see how it performs. Maybe i get white noise but for now my listening hours are 1-2 hours per day.

You'll know the white noise when you hear it - it is truly horrible! Dropouts are definitely better.

I have short drop outs only, quite infrequent: no more than once of twice a day for a 5 to 6 hours listening.
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.

So, white noises may be due to system buffering issue?
