Hi,

  here's the new revision of the Audiotrak Prodigy 7.1 driver.  The 
driver now initializes correctly for the 24.576Mhz crystal and also I 
have added some more controls for adc oversampling ratio (in theory 
should be changed automatically to 64x at 96Khz sampling rate) and dac 
de-emphasis.

  The initialization sequence of the WM8770 has been modified to reduce 
the pop noise at startup (now it's almost nono-existant). Also the 
volume control updates now only at zero cross automatically to reduce 
again the noise when changing volumes. I think the aureon driver should 
also benefit from these two so I include a patch for the aureon.c too.

 Finally there is some misconception in the aureon & prodigy drivers: 
the codec chip does not have a Master control as it appears at the 
mixer. Instead the master control just updates the 8 volume controls of 
the individual DAC at the same time. Probably the best way is to add a 
virtual master control (ie that we update the volumes of the dac with  
<master attenuation> + <specific channel attenuation> ).

As I wrote some days ago, the default buffer/period rates that 
alsarecord uses at 44.1KHz and lower sampling , locks hard the kernel. 
Have no idea what is it/how to fix it whatsoever.
