That is a legal issue you might run into. If you do Dolby Anything in software you will likely need permission from Dolby Labs. If it only involves flipping a bit to turn something on in the Extigy, that would probably be fine, but IANAL. > He doesn't know how to update the firmware.... I do.

On the Extigy which I recently purchased, one of the first things I did was download the latest firmware and drivers for XP. It appeared to have actually flashed new firmware into the Extigy, since before the firmware upgrade the Extigy didn't want to turn on CMSS until the Windows drivers had initialized it. Now, I can turn it on at any time, even when it is not hooked up to a USB port on the computer. However, I have yet to actually see if it has any effect when the Extigy is working in stand-alone mode. The fact that the behavior changed indicates something had to have been changed internally in the Extigy. Maybe it is two-part, some new firmware flashed into in the Extigy, and more gets downloaded on initialization? > The linux usb and sound support is not exactly like ours. > It can only play at 48KHz..

I think all the Extigy actually does is 48KHz D/A and A/D conversion, and Dolby Digital 5.1 decoding (via an internal Zoran decoder). -- Chris Dillon - cdillon(at)wolves.k12.mo.us FreeBSD: The fastest and most stable server OS on the planet - Available for IA32 (Intel x86) and Alpha architectures - IA64, PowerPC, UltraSPARC, ARM, and S/390 under development - http://www.freebsd.org No trees were harmed in the composition of this message, although some electrons were mildly inconvenienced.
