I committed the 5 year old envy24 driver by Katsurajima Naoto. Konstantin Dimitrov spend some time to fix some bugs and to add support for some more soundcards. Currently supported / known to work are:

• M-Audio Audiophile 2496


• M-Audio Delta Dio 2496


• Terratec DMX 6fire

Reports about other working devices are welcome.

There are some known problems too, they are related to vchans, kldunload-ing of the driver, 24bit support, and some mixer problems. People which want to help or add support for their soundcard can have a look at the already collected datasheets:
