Here's a strange one. I bought a few USB Sound Cards on Ebay to test out on AROS and MorphOS.

The first one that arrived as a C-Media USB Sound adapter, which AROS and MorphOS detected just fine. In fact it showed up under AHI!!!!

On the down side, once I selected it, nothing happened. No sound would be produced, and on my MorphOS machine, MP3 files would no longer load and play.

So I'm wondering, are these devices truly supported?

Here's a page with a picture of it.
