It was working ok until I upgraded recently my MacBook (as the player host) to a newest one for 10G network connection. My DacMagic 200m will turned off after idling for a while, then Audirvana could not have the DAC recognized (usually next day) except for other devices such as my TV and MacBook or even my Blu-Ray player, I confirmed on the Audirvana the music has completely stopped, it will only start to recognize my DACMagic 200m until the MacBook restarted since close/reopen Audirvana or turned off/on the DAC would not help.
It is quite annoying for I have to do this each time to use Audirvana (3.5) .
Any advice?
