I am not quite sure wether this belongs in here or in the darwin-drivers list.
The Extigy is a usb sound card from Creative Labs, which appears to
not comply to the USB audio standard to not work properly with MacOS
X. I tried one recently, it got me some popping and crackling HAL
audio output and a working MIDI-out device every 1 out of 20 tries.
Also, with the Extigy plugged in, the computer crashed sometimes on
startup.
You should report the crash as a Radar bug. Apple will fix that.
They will probably be interested in finding the other problem, too;
although, the crackling could be a hardware problem (24x96 I/O rates
are getting pretty dense for USB I).
Now I was wondering if there was any interest in an OS X driver for
it - I have tried ALSA/Linux drivers for the card which worked fine
and are just minor adaptions to generic USB audio drivers. I know
the Extigy is by far not the best audio card and does not deliver
the claimed 24/96 quality. However, I think it would still be a
bargain if we could get multiple outputs and MIDI connectivity from
a single $120 USB device. The guys from usb-audio.com also claim
that you could get low-latency audio from the card with their
ASIO/Windows driver.
Is anyone interested in writing such a driver? I could help with
some development, I wrote a USB MIDI driver for BeOS a while ago. If
we could form a team of developers willing to write such a driver,
I'd buy such a card and help writing.
It might make more sense to fix the existing USB Audio and MIDI class
drivers. They should be in the Darwin tree someplace, right?
