I had a few fairly basic USB audio output devices lying around doing nothing and I wondered if they would work in OS 9. Here's what I've got:
- Plantronics USB Adapter-01 (headphone and mic jacks)
- Zalmann ZM-RSSC (5.1 audio capable, three x 3.5mm headphone/line out jacks, plus coax/optical out)
- Xitel MD-PORT AN1 (line out jack only)
All of these show in System Profiler as multiple device elements recognized as USB Audio and USB HID. They either won't show in the Sound control panel at all or not work if they do though. In the case of the Xitel, the manual for it clearly states that as long as you're running a minimum of OS 9.0.4 and Apple Audio Extension 1.0.5 or higher, it should work. I'm trying this with 9.2.2/2.4 combination, which you'd think should still work.
Am I missing something? I'm not expecting all of these devices to work, but the Xitel absolutely is supposed to. I'd like to put one of these to work as a basic sound output from the 9serve, which has no built-in audio, or the G4 Mini on OS 9 if we can't get its built-in sound output device to function.
