I own the Echo Indigo output-only card, and I can confirm that this
works in Linux just fine. However, it is not "out-of-the-box." You
must install the ALSA firmware package for this card to work.
Otherwise, you won't see anything about the card in dmesg,
/var/log/whatever, etc.

Back when I was trying to get it to work, I emailed the author of the
driver. His first name is Giuliano (forgive me if I misspelled it).
Here is a cut from the email he sent me:

It's on .

You have to install the hotplug scripts (they should be installed in
/etc/hotplug/ and /etc/hotplug.d/), alsa-firmware and alsa-driver.
Also, there is an entry in /proc that must point to the main hotplug
script. A script in /etc/rc.d should set it up at boot time.

No, alsa-firmware only installs the firmware in /lib/firmware .
You have to get the scripts from or download the appropriate
package of you distro.
Also, check what /lib/firmware is. Usually the scripts (firmware-agent
IIRC) looks for firmware files in /lib/firmware , while alsa installs them
in /usr/lib/hotplug/firmware . Fix it with a symlink.


So to sum it up, get the firmware, make sure you have the hotplug
scripts (which you probably already do), and make sure you make a
simlink from /lib/firmware to /usr/lib/hotplug/firmware.

Hope this helps,
