Hey,
I've been having this problem for years now and finally decided to ask for help.
Whenever I add a second input - and load a second instance of audio input on a remote (slave computer) system - audio stops working. Bypassing the second audio input plugin restores the audio. Basically I can only use one send/input or my VE Pro doesn't work.
Master:
Mac Pro Late 2010
Cubase 8.5
Slave:
Macbook Pro Late 2013
VE Pro 5.4.14074
Thank you,
Yoav
