Ethernet streaming and occasional white noise on Windows

[AlexS]

Devialet have a Windows 8 laptop of ours which has the 'noise problem' and with which they can reliably reproduce the problem. We are waiting to hear from them about the results but of course they are on summer shutdown at present!

Now this is indeed good news. And no more excuse for Devialet not to fix this once and for all.
@oxfordaudio, what was the "white noise" pattern exhibited by this this Windows 8 laptop? Was this just lengthy listening sessions, which eventually resulted in the issue? Or something else?
