Envy24 driver committed to -current.

[Alexander Leidinger]

Hi,

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 at

Since there are still some bugs, no MFC is scheduled yet. People which
want to give it a try can copy the entire soundsystem from current, it
should also work on 6.1.

Bye,
Alexander.
