Hello,
I am a "long time" user of VOX.
I read you did a great job of reconnecting VOX to Airplay since El Capitan mess up... Thank you!
I installed the last version of VOX, and still have many problems of audio glitches.
I checked everything you advice in the support page. I even set it for music pre-load and everything......... no result.
Audio glitches as soon I make any other use of my MacBook Pro (13-inch, Mid 2009 2,26 GHz Intel Core 2 Duo 8 Go RAM) than listening to music.
It seems to me it is not a matter of network (wifi...) because I tested with version 0.3 beta 1 of VOX (!), and set the computer audio to Airplay, that works perfectly.
I just tried to set VOX version 2.7.3 audio to "same as system", and set the computer audio to Airplay, that also works perfectly!!!!!!
Hope this helps you. Thank you.
