XCore Exchange

Turns out my big problem was using MacOS High Sierra with the latest updates. I reverted to El Capitan without the latest spectre & meltdown fixes and I can get 96kHz. 192kHz is glitchy but I actually only need 96kHz at present. When I looked on the scope the 192kHz setting was only getting an LRCLK of 150 ish khz so I think there is an underlying i2s timing issue there I need to dig in to. Perhaps changing to the frame based i2s master is better.

Check also which device is master: setting my device to clock master is the only way to get a glitchless audio. That seems related to the fact my application is talker only, but I'm not AVB expert. Wonder hwo is...
