USB audio in Haiku

The last time I looked at the drivers and install files and such, there was an entry for USB Audio. As both my nVidia chipset motherboards have HDA audio (which is shown, but nothing is ever heard, no matter what I do), I’m hoping plugging in a pair of USB speakers might be a quick work-around.

Has anyone tested this driver and/or know how to get it working?

At the moment I’m working on USB Audio driver for Haiku. Please contact me by e-mail: zharik-at-gmx-li if you have such hardware. I need some info about USB audio devices topology. Thank you.

PS: Current implementation of usb_audio in Haiku source tree is just a BeOS sample code for USB isochronous transfers and I know nobody who has push it to work under BeOS.
