Do your setup the way you want it with your audio and then go to the preferences and hit SAVE!!!!!!!!!

The SAVE button SHOULD be in the left hand corner of the dialog box and has been there for several Metro versions. :D

However I have no idea what the OK button is for. Either you save the changes or you cancel.........does it actually serve a purpose?

Audio preferences are saved automatically. There is no need to save preferences for this.

Personally, I have never seen this happen except when a USB Audio Device has been unplugged (off-line).

The OK button in the preferences dialog sets the values as specified in all panes but does not save them. This makes it possible to experiment with say, buffer settings, without committing to them every time Metro is started.

I think if there is a driver for the USB audio device then it should be installed. USB audio devices are inherently out-of-sync. In other words, output knows nothing about input and input knows nothing about output. This is resolved by installing the driver that came with the hardware and therefore it is not recommended to use the built-in Apple USB driver.

I doubt this is related to the original problem of the audio device not sticking.

I will check using a USB audio device that I have, if I can reproduce the non-sticking problem.

You say you select your output device in the Core Audio dialog. Why not select it in the Digital Audio Setup dialog?

Have you tried temporarily removing the Metro Preferences file from its default location.

If the preference file is corrupt then this could cause what you are seeing.

jonrandall setup..........

System Settings

Default Input (EZbus ) Default Output (Ezbus )
System Output (Built-in audio controller)

****************************

I assume this is the audio side of the audio/midi setup window in OSX?

can the system output be changed to anything else?
I have no external devices like an ezbus but I do notice that the system output is a popup, so I was wondering if it is changeable in your setup?

also the selected audio device looks like a pop up too. can you change it?

>make all things as ambiguous and unintuitive as humanly possible

this may come down to a debate between your pirhana and microsoft so we won't go there.


I do wonder if there is a problem somewhere in the mac audio setup if there are a few people here suffering from audio setup problems once a 3rd party device is added to the mac?

Then again there are probably just as many who have succeeded in the attempt.

I found the midi setup completely effortless when finally getting a hold of a usb midi interface and installing the driver.
Maybe there are a few buggy OSX audio drivers out there still.

I will acknowledge, after seeing the screen shots, that this is probably a bug in Metro.

I will also bet with 99.9% certainty that your input and output are not in sync and you probably cannot make them in sync. Not good for an audio interface that a musician is doing multi-tracking on.

It is very hard to diagnose this problem without the hardware.

I have exactly the same EZBus device, and I never had any problems with (this part of) the USB sound thing.

One thing that I did and that hasn't been discussed here is that I do:
+ "Modify Instrument and busses"
+ Select "Make instrument reflects MIDI setup document"
+ Click OK
+ Save the prefs again.

And my settings stays pretty much as they should; I must say I haven't played a lot with the audio part of MIDI recently, but as far as the settings are concerned, they stick :-)

I don't have a special driver either; plain stock 10.2.6!
