Mac Mini (El Capitan) -> USB -> Dev200 problem

[canyelles]

I don't get those every time either, sometimes there is nothing in the log.

Sometimes the distortion seems to coincide withe log messages like this (100s of them)

I have just had an email from Devialet in which they say it has nothing to do with them, must be changes Apple have made.
They might well be correct, there are plenty of complaints on the internet about El Capitan.

One difference between you and me is that my mini is headless, I am controlling it using screen sharing from an iMac.

I am thinking of buying an apple tv and using airplay.

Can't use AIR, can't use USB, here comes Airplay.
