Smells like a gradual overflow/corruption of some memory buffer, proportional to the amount of data fed to it. Please keep on sharing your observations with Devialet. One day they may have a revelation.
Exactly. It is an accumulative overflow in HD which dissipates for a while after you switch back to 16/44.1 but builds up again on return to HD.
Probably more speedy, in my experience, using wifi rather than ethernet.
Even if you disable all wifi sources and wifi via the configurator and make things as minimal as possible, it is still there after 3 or 4 hours in HD using ethernet, in my experience.
All (especially those who can recreate the white noise at will),
This morning, Roger from Devialet has sent me a new BETA version (2.1.4-beta1), and asked me to test.
The "problem" is that with me, the issue is really sporadic: with my switch from Foobar to Jriver, I've not encountered it for a month.
Feel free to reach to Roger, to assist with the testing.
Alex - I also have a copy of 2.1.4-beta1, although I have only just discovered this having logged into the Devialet support page and found it was already there! It was an update sent 10th December to a previous query that I was unaware of. Maybe I missed / deleted the notification email by mistake? Maybe I didn't get a notification email? Strange, as previously I have always picked these up without any problems. Anyway, I have it and can reproduce white noise almost at will. We shall see......

Keep us posted. One day, they will fix it for good, and we'll never come back to this thread most of us must be tired of.
BTW, if the issue still happens to you with the new version, try (temporarily) disabling your Anti-virus program (if any), and automatic Windows Updates.

Alex - Suggestions noted! It looks like I should have some time this weekend for some seriously long period AIR testing. I'll report back.
I have had an interesting day trying AIR 2.1.4-beta1. The good news is that it looks like we are finally getting somewhere with this one. The bad news is that the issue has not 100% gone, or not for me at least. The further good news is that this is no longer a random type event, but now shows very specific behaviour.
I was running JRiver, WASAPI, with exclusively 24bit music. No issues at all for 1 and a half hours, the music then flicked into white noise, temporarily, then recovered and continued to play for two hours with no problems. The key point is that this white noise event occurred exactly at the moment that my PC switched into screensaver mode, although it had gone into screensaver mode earlier with just a minor glitch in the smooth running of the music . Leaving the PC in screensaver mode, using an iPad for track selection, no white noise issues at all. After a period of running, I tried a few runs just leaving the PC playing as it went into screensaver mode, and 9 time out of 10 this resulted in a white noise event, either just a few second of white noise, then recovering back to music, or sometimes just a full switch to white noise. I tried the same thing with 16/44.1 material, an each time the switch to screensaver mode caused a small jump in the music, but nothing drastic and no white noise.
I'll try a few more things tomorrow. Based on today's results it looks like AIR 2.1.4-beta1 is a fairly solid performer, except for whatever my PC is doing to upset things when it goes into screensaver mode. Do any of the IT wizards on here have any idea what this might be?
I guess there is the obvious workaround of setting the screensaver to 2 hours or something? Although I do sometimes wonder if letting the machine go into screensaver mode is actually slightly better for sound quality, with less PC systems running? This suggests another workaround, that is to let it go into screensaver mode once (remember I had 1 and a half hours running before the screensaver mode caused this event), then leave the PC alone and just use iPad control.
If someone can work out what is happening during the switch to screensaver mode, we might be able to get nearer to a 100% robust cure.
Any ideas?

Hi Confused
According to Support, the new beta version of AIR also fails to work with Mac gear. For months now, ethernet or wifi, I have had predictable white noise after as little as 10 minutes via wifi/hires and as much as 4 hours via ethernet/16/44.1 with a minimalised configuration file and all wifi turned off.
The commercial imperative to press on with Phantom and Dialog perhaps takes precedence over getting things right for existing customers who have funded part of their success.
I have trying AIR 2.1.4-beta1 again this morning. Slightly different results from yesterday. Today, every time the PC switches to screensaver mode, I get the white noise. I have now tried every option in the power management settings to see if this makes a difference. There was one case when in "power saver" mode that it did manage to go into screensaver mode without white noise, but just once, three or four other times, straight to white noise. In "high performance mode", white noise ever time. I have now set the screensaver to mode to "never", to simply stop it going into screensaver mode at all, I will now see if will do a long run white noise free with 24bit WASAPI material.....
I disabled screensaver (screen always on) but still get white noise - both ethernet and wifi - using 2.1.3 - after as little as 10 minutes, with Mac.
Could you try it with screensaver disabled?

Confused, what if you simply turn the monitor off, prior to playback? This way, you could still take advantage of screen saver at other times.
On the Internet, some people recommend turning off screen saver for optimal playback, but it never caused issues for me. My instances of white noise were never connected to it.
