I have a client on Mac saying that audio playback is not possible with his Digidesign HW HD card and Juce. I send him the latest JuceDemo and he has the same problem.
Does anyone have seen this before? Is there anything I can have him try?

Configure the AudioDeviceManager to use the device for output?
that’s what he did, he fiddled with the active outputs on the demo but no sound. A previous release of Juce played fine on his machine.
try to find out which juce patch introduced the issue, maybe not the answer you want to hear, sorry 
You say it ‘played fine’. Does it now? Maybe he upgraded his drivers and that has broken something.

I’d definitely put my money on this being a driver issue. The CoreAudio classes are very stable and have been for a long time - this doesn’t sound like a juce bug to me.
hmm, it is not a driver issue I think. Just got a message back from the client. I have send him two versions of the JuceDemo, version 1.53 build 61 and 2.0.21. The 1.53 works, but 2.0 not.
Is there anything I can have him try? I saw there are a lot of changes in the core audio file, so where to start?
Most of the changes to that class have been pretty small - if you had the device yourself, it’d probably be easy to just roll them back and see when it stops working, but if you have to send exes to a client to test, that’s a PITA. Not really sure what to suggest… Perhaps a binary-chop between the 1.53 version and the current one? Can’t take more than a few iterations to find the culprit!
I did just have a quick scan through the diffs and there’s really not much in there that looks dangerous. There is a change from last year (12/08/2011) which detects disabled devices - it could be that the digi drivers fail to implement that correctly, and the device appears to be disabled?
yes, I saw that change too. I’ll send him a version just before and after that change and report back.
