Combining two AVB/TSN boards in Mac OS

Postby mx12 » Mon Aug 14, 2017 1:56 pm

We have followed the AN00202 (Gigabit Ethernet AVB endpoint example using I2S master) to implement a 8 channels talker AVB card. Its works fine when connected to a Mac computer.

Now, we would like to connect two devices and use them together. On Mac OS, you can aggregate audio devices. The problem: I never managed to make it work. What I get is either 8 channels ok, 8 channels muted, or 16 channels muted. No error message, nothing preventing me that something goes wrong.

Does anyone already tried that? Can anyone give me some help?
Thanks!
Vincent
