Is the Echo Indigo IOx card supported?

[fourfour]

I am referring to the ExpressCard version of the Indigo IO card. I've found mention of this card in the ALSA changes list at

http://www.alsa-project.org/main/index. ... 19_v1.0.20

but the card is not listed in the ALSA sound card matrix. The situation is similar for the Echo Indigo DJx card.
