Ethernet streaming and occasional white noise on Windows

[AlexS]

PS. I'm speculating, but in theory it's possible that AIR 2.1.4 beta4 is heavier on the CPU. Given that you were getting issues before with the screen saver enabled, there may be moments when your CPU is exercised to the limit, or else is frequently caused to transition from a low power consumption mode to a higher one, or vice versa. For optimal music playback, some recommend changing Window's power option to "High Performance". I've never done it myself, since I was able to solve all stuttering problems through disabling Windows Defender and increasing JRiver buffers, but you may try giving this a shot, and see if it helps.
