Same result. A quick check at the IRQ list reveals the Echo3G is now alone
at IRQ 16. But still won't show up in the playable devices list.

Hm, not all drivers are happy with an IRQ above 12.

OTOH, some weeks ago I had a similar problem with a soundcard from a
different vendor. The card was correctly listed in the inventory of
the BIOS, the device manager showed the card correctly and drivers
loaded. But neither sound nor accessible from any Windows program.
After a long search I found that I installed the wrong driver, same
vendor but a different model.

Mike, have you checked with Echo Audio that you have got the right
driver for the combination of card and operating system?
Are all patches for the motherboard installed?
Does the Gina driver support Athlon 64?
