HDX Core Audio

[Mount Royal]

What's the consensus these days regarding appointing HDX card output as OS Core Audio? Pro Tools 8 was the last time I had any success using Pro Tools Main out, a Digital 192 at the time, as Core Audio. It worked well at the time.

Thank you,

Maybe I don't hear the question right.

But it is so much easier to run OSX sound out of the mac into the 192.......


That way if a new Mac OSX breaks the feature you don't have to depend on Avid to fix the issue with software.

Because we all know that might not happen right away.

This sounds exciting, but I need a bit of hand holding on the method, I'm afraid.

Are you suggesting that Mac OS audio leaves the MacPro's sound card digitally, enters the 192 IO digitally, and leaves the 192 IO either via analog or digitally? Are you also saying that this 192 thru-put is available outside of Pro Tools being open or active?

To be clear, my question was not how to record audio from the MacPro's analog audio out put into Pro Tools.

The prospect you describe sounds exciting, but I've never heard of such a thing - my ignorance probably.

Many thanks,

John Caldwell

Yes this is the way....

What I assumed you wanted to do was take Mac OS sounds and iTunes, YouTube and the like and output them through your studio speakers...is this right?

Precisely. You've named the tasks I lump with Core Audio functions, or that's what we used to call it.

If you can comment, how do you suggest getting from the MacPro to the 192, and what Hardware Setup is needed in PT to allow the 192 to pass audio, even if Pro Tools is not launched?

Appreciate your insights,

....simply use "Avid HDX" as core audio output in
system preferences>sound>output..AVID HDX
should work fine , no setup in PT needed

So I left Mac more than a year ago, (as my main rig anyway I still have a laptop for mobile setups)

Core Audio was broke from 10.8.5 till 10.10.5, and even then it still didn’t work from what I found.

It is supposedly been fixed on 10.12 but I have no way of knowing.

The easiest way (for me, anyway) was to not depend on Avid and utilize a hardware solution to forgo any software blunders (Avid)

This is what I mentioned above

Computer Hardware Audio out, to 192 in (in my case in to a monitor controller) then out to my studio speakers

Thank you and continuing with that theme, do you depart the computer hardware in analog or digital signal? Is there a way that we can "program" the 192 to pass audio, from Input A to Output B, without PT being open?

I should know this but don't.

So to clear up a few things Core Audio for Avid HD Hardware was broken with Yosemite
But currently as of PT 12 something and OS Sierra it is working again. I use it all the time on my system configured as (below in sig line )

Yes it works when PT is not running. In fact I believe it only works when PT is not running .

With the System Preferences Sound window open, I can watch the Avid HDX option disappear, and then reappear, as Pro Tools is opened, and then closed.

The prospect of routing CPU output digitally thru an interface is nice. As is argued above, Core Audio, and its unreliabilities, could be bypassed. I haven’t looked into the details of how one could route Optical In to AES out of a 192 interface, but that would be the best option for my setup.
