I spent an interesting morning trying to test AIR 2.1.4-beta1 to destruction. I was up early this morning, and set JRiver up with a large 24 bit playlist. Screensaver now disabled. The system ran without white noise from 5:55am to 10:25am. So that was about 4.5 hours stable running at 24bit WASAPI, only interrupted by myself in the end, not white noise. To be honest, I was not listening through this entire period. (1 shower, 1 quick visit to local shop) However, when I was listening there were no issues, no glitches, nothing. I then tried running what is my least stable way of using AIR, that is with iTunes running 16/44.1 material, PC soundcard and AIR GUI settings both at 24/192. Yes, I know this is not sensible from an optimum sound quality point of view, but in the past this is a set up that gives fairly random white noise, I was trying to see if with the screensaver disabled would AIR 2.1.4-beta1 be stable even in this condition. It then ran without issues until 11:15am, then a short burst of white noise, then OK until white noise at 12:06pm, 12:10pm, 12:16pm. In each case short bursts. (A clear demonstration of @AlexS' statement that once you get white noise you should reboot, as one event plants the seed for many more. The PC was not rebooted during this test.
So with that done, my next plan is to try with the anti virus off per AlexS' and Thumb5's posts above. This will have to wait a few days due to festive season distractions!
Apologies if I'm making some wrong assumption here but we are hearing this issue on both PC and Mac right? Is the behaviour roughly similar from both? If so this might rule out OS-specific settings for power saving, antivirus or screensaver etc.
I've still yet to hear white noise but I do get silent dropouts from my Windows 7 (64 bit) PC with JRMC 19, seemingly random but usually lasting about 30 seconds or so and then it continues playing. Nothing in the Windows logs to coincide with it. Library is on a mapped drive from my Qnap NAS (which could be the culprit). It's very possible my problem isn't the same as the one in this thread.
I am also getting very occasional drop-outs playing 16/44 material via AIR on my Mac. The Mac is wireless to my router, but the Dev is wired. Sometimes AIR just stops (the menu bar icon goes grey) but can be reconnected immediately and continues to work. Sometimes there's a very short "stutter" in play-back.
This is not the same problem I used to have where AIR would disconnect and would not reliably re-connect. That seemed to be a feature of the wireless interface on my old MacBook Pro as it was cured by using an external wireless adapter. But I'm now running a different version of AIR (2.1.3 vs 2.1.1) on new hardware (a brand new 15.4" MBP - not through choice, though it's very nice, but because my old machine finally lost the battle against the GPU un-soldering itself due to over-heating) and a new version of OS X (Yosemite vs Mountain Lion).
I have a feeling that the drop-outs I'm hearing now are unique to AIR 2.1.3/Mac/Yosemite, as other people have reported similar behaviour. I see the same console output about buffer clipping (IIRC) as reported elsewhere.
I haven't ever heard white noise, and long may that remain so!

I have experienced the same
both Devialet and Macbook Pro are connected via WiFi
but no white noise in my case
As an update to my earlier posts, over the last week I have been using AIR 2.1.4-beta1 fairly extensively, with the soundcard GUI set to 16/44.1 and PC screensaver now disabled. (Using JRiver WASAPI the PC soundcard settings are ignored anyway). I have been using iTunes during periods where I wanted access to some of the playlists etc. that I have set up there, and JRiver WASAPI for the more serious listening where maximising sound quality is the priority. Zero white noise issues so far.
That sounds promising, good to hear. Fingers crossed...
Confused - will be interesting if it's fixed with your screensaver enabled too. I think AIR should be expected to function perfectly with default or commonly-used PC settings and functionality.

Confused, so, no white noise with 16/44, but still some occurrences with 24/192, even with screensaver disabled? Please confirm.
Have you tried to disable the anti-virus?
The connection of the problem with screensaver is a mystery: mine is set to 10 mins, and I've never encountered even a hint of a hiccup in playback.
However, with JRiver, I've run into playback stutters due to Windows Defender's installing its latest virus definitions and running a scan. I've disabled this behavior, as well as automatic Windows updates.
Gentlemen, this thread was opened for white noise on Windows only. At that time, there had been no reports of a similar problem on the MAC. Just to make sure we're speaking of the same problem, white noise is very loud hissing sound, which occurs all of a sudden, and may or may not temporarily recover back to music.

AlexS. Since disabling the screensaver and only using iTunes with the PC GUI set to 16/44.1, i have not had white noise, including JRiver WASAPI 24bit usage. The last time I had white noise was when using iTunes 16/44.1 with the PC GUI set to 24/192, which is not a particularly sensible thing to do anyway. So it looks to me as if the latest beta AIR, although not 100% bullet proof, is a significant improvement.
Gotcha AlexS. the thread's so long I wasn't sure if there were reports of Mac users with the same symptoms so apologies for confusing things. Seems there do seem to be multiple issues with AIR though with varying symptoms.
