+ * - we reuse the akm4xxx_t record for storing the wm8770 codec data.
+ *   both wm and akm codecs are pretty similar, so we can integrate
+ *   both controls in the future, once if wm codecs are reused in
+ *   many boards.
+ *
+ * - DAC digital volumes are not implemented in the mixer.
+ *   if they show better response than DAC analog volumes, we can use them
+ *   instead.
+ *
+ *   Lowlevel functions for AudioTrak Prodigy 7.1 (and possibly 192) cards
+ *      Copyright (c) 2003 Dimitromanolakis Apostolos <apostol@cs.utoronto.ca>
+ *
+ *   version 0.82: Stable / not all features work yet (no communication with AC97 secondary)
+ *       added 64x/128x oversampling switch (should be 64x only for 96khz)
+ *       fixed some recording labels (still need to check the rest)
+ *       recording is working probably thanks to correct wm8770 initialization
+ *
+ *   version 0.5: Initial release:
+ *           working: analog output, mixer, headphone amplifier switch
+ *       not working: prety much everything else, at least i could verify that
+ *                    we have no digital output, no capture, pretty bad clicks and poops
+ *                    on mixer switch and other coll stuff.
