f0b43758d7 - fix memory leak, when "number of adcs" != "number of dacs"
- fix multiple initialization of the first codec (support for more than
  one codec should be added in the future)
- use spicds instead of ak452x module

347edd7ee6 - fix memory leak after "kldunload snd_ak452x.ko"
- fix "No sound in KDE":
  The problem is related to the implementation of Envy24(1712) hardware
  mixer support in the driver. Envy24(1712) has very precise 36bit wide
  hardware mixer, which is superior that vchans (software sound mixer in
  the kernel). The driver supports Envy24(1712) hardware mixer, so up to
  10 channels (5 stereo pairs) can be playback simultaneously.
  However, there are problems with the implementation of Envy24(1712)
  hardware mixer support in the driver, one of them is the problem with
  "no sound in KDE":
      When playing back several channels simultaneously and
      stoping one of the channels, sound starts to stutter and
      plays at very low speed.
  Another problem is:
      Playing back simultaneously more than one 24bit/32bit
      sound file or 16bit sound file and 24bit/32bit sound
      file doesn't work as expected.

ce356b7017 - fix compatibility with newer versions of FreeBSD
- fix all warnings during compilation
- fix obvious bugs
- add support for more cards

Now supported:
 - M-Audio Delta Dio 2496
 - M-Audio Audiophile 2496
 - Terratec DMX 6fire

Known bugs (detected by Nokolas and Stefan):
 - $ kldunload snd_ak452x.ko
   Warning: memory type ak452x leaked memory on destroy (1 allocations,
   64 bytes leaked).
 - No sound in KDE: Everything works fine at the console but when I load KDE
   (3.5.3) the sound stutters and plays at less then 1/2 speed.
 - 'mixer: WRITE_MIXER: Device not configured' The message repeats x
   times at system startup, x = whatever hw.snd.maxautovchans is set to.
   (this is because only vol, pcm and line are supported, but the driver
   shows more than those mixer devices and setting those additional mixers
   results in this error message)
 - vchans don't work
 - 24 bit playback not supported (only 16/32 bit)
 - after kld(un)loading some times, the card fails to be probed until reboot

12ab72d345 dd the envy24 driver as is to the tree. It's not connected to the build
yet. More commits to follow.

I got no response from the author, but since the driver is BSD licensed
I don't think he will complain. :-)

I got it from http://people.freebsd.org/~lofi/envy24.tar.gz
