sadly: no.. well the chip gets recognized now:
$ aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: NVidia [HDA NVidia], device 0: Cirrus Analog [Cirrus Analog]
  Subdevices: 1/1
  Subdevice #0: subdevice #0

and alsamixer also shows a bunch of channels now as well as 
"Card: HDA NVidia                                                                                                                                            
Chip: Cirrus Logic CS4206"

but i can't get any sound eventhough all channels are unmuted and turned up to 

i also aplay -Dfoo file.wav again, where foo = default,front,surround40,.... , 
but i always get: aplay: main:608: audio open error: Invalid argument
