Hi,

Last evening I found way how to use Philips ADC instead of AC97 on 
Audigy 1.

Attached patch is tested only on Audigy 1 player (not tested on 
Audigy 1 Platinium, Audigy 1 Platinium EX, Audigy 2, Audigy 2 
Platinium, Audigy 2 Platinium EX), but I think it should work for all 
Audigy 1 and Audigy 2 cards, can some one test it ???

Modification:
 - disable routing from AC97 line out to front speakers.
 - AC97 ADC is used only for Mic playback and recording
 - Philips ADC is used for other analog playback and recording 
(Analog Mix Playback Volume, Analog Mix Capture Volume)
 - removes unused AC97 controls (is phone used ???)

Advantage:
 - better Line In, Analog CD, Aux sound quality playback and 
recording (I hope that Philips ADC is better than old AC97 ADC)
 - similiar mixer as used on Windows
 - simpler mixer
 - you doesn't need set capture source to be able listen or record 
analog sources - I think this was confusing for many users
 - fixed small bug in MIC ADC buffer recording (alias device 1 - 16 
bit 8000 Hz mono)

TODO:
 It seems that Audigy 1 can do 24 bit/48kHz recording (and I think 24 
bit /48 kHz playback too) using TRAM playback and capture. Philips 
ADC is connected to DSP and trasmit to DSP all 24 bit and I think 
that Philips DAC is connected in same way.
