USB Audio on OS4 Classic

Is anyone using some USB audio devices with the Deneb card on OS4 classic running Poseidon? I have the problem that the device is detectet but theres no AHi unit in the prefs to choose. The device works fine on OS3.

Yup, I'm using it just fine.

It didn't copy a necessary file for some reason so I had to copy it from the 3.9 installation. I think it was usbaudio.class or something like that, go digging on your 3.9 and see if it's missing on your 4.0.

When that's done it should work just fine (mine does).

@Spirantho

This is odd. I checked everything twice so I have all the files that I have on OS3 too but the device does not appear in the AHI prefs.

I got it. OS4 needs a physical audio driver which is of course not available by Poseidon. All I need is a usbaudio.a.main file.

@DJBase

That's it! I just renamed another .a.main file I think. :)

Ouch The purpose of the .main file is to provide access from PPC programs to 68k libraries/devices.
Under OS4 programs expect libraries/devices to provide a "Main" interface, but 68k ones aren't providing such a thing. Purpose of this main interface is to contain pointer to functions provided by the library/device (I doubt you renamed another one and it worked execpt if this was one for a similar library/device that provided the exact same functions at the exact same offsets).
You can however generate one if you have the corresponding fd file.
For example Thomas Rapp described one way to do it on his web site : How to create PPC stubs for M68K libraries

I'm pretty sure that Spirantho has patched his .main file the last time...

Good job your memory is better than mine. :)
