Still no further forward to sotring this out, but it does seem like its a software issue between logic and the motu software,
If i go mac- system pref- sound- sound Effects, and tell it to play sound effects through Motu 828mk2, then click on the alert volume slider, then i hear the mac beep soundeffect...
If i then open the Motu audio setup, and change the default stereo out to ANYTHING else, then i get the output leds light up on the front of the 828, and the sound comes out of said output all good!
I can also change the phone assign to the same output, and still all good!
How ever..... if i open Logic, and change the output on an audio track for example, then change the default stereo output in motu audio setup, i get nothing, the output leds dont light up, i get no sound, and the phone assign will not work either.....
But..... if i change the output on an audio track in logic to either the s/pdif outputs, or to the adat outputs, then i get the output leds light up on the motu, and i can also hear those outputs if i route them in motu audio setup-phones assign.....
WTF!?
Oh and i have exactly the same issue in soundtrack pro....
This is driving me insane, i have the latest motu drivers/updates etc, is there anyone here who runs logic 9 and a 828 mk2 that can send anything out of any output apart from the main outs...??
How can you record to an external source for example, if monitors are connected to main outs!?
