AIR streaming - occasional short skips

[AlexS]

A few days ago I returned to using AIR instead of DLNA, and I noticed a tiny 'blip' of no sound every 15sec or so.
I had to increase the hardware buffer size in the AIR settings to 500ms to eliminate it. (The one where you have to unlock the setting to change it). Bit disappointed that 250ms wasn't enough.

I tried increasing all other buffer size options, but this was the only one that worked.

Oh, my buffer is already 2 seconds big! And, to be honest, in my case, the problem only happens about once a week. Probably, related to some computer activity, but I can't figure out what it is.
I'm on the border of buying a JRiver Id NUC, and starting feeding Devialet via USB.
