the geomon page is not being updated anymore and has been reinvented to
be the homepage for the online docs.

I use a maudio quattro and we are having good success with the driver.
Currently you can use all four channels for playback and recording
seperately. I have successfully recorded a stereo stream for 2 hours
without dropouts with this device.
It works with JACK too although it is experimental and not complete.
As long as the manufacturers make it compliant with the generic code it
is currently supported in ALSA. If is is not compliant it can be fixed
if you are prepared to debug.
