With my new Nforce 570 i'm unable to control audio while using alsa.

I have configured my .asoundrc per this guide.   I have my audio device 
set up to be ALSA:mixed-analog and the mixer to be mixed-analog.  The 
front end gives the following error messages:

2007-02-01 19:09:08.547 AFD: Opened codec 0xe770fb0, id(MP2) type(Audio)
2007-02-01 19:09:08.763 Opening ALSA audio device 'mixed-analog'.
2007-02-01 19:09:09.036 Mixer unable to find control Master
2007-02-01 19:09:09.036 Mixer unable to find control Master
2007-02-01 19:09:09.037 Mixer unable to find control Master

I have tried setting mythtv to control both the master and the pcm but 
neither of them seem to work.

Here is my modprobe.conf sound section:
# ALSA portion
alias char-major-116 snd
alias snd-card-0 snd-hda-intel
# module options should go here

# OSS/Free portion
alias char-major-14 soundcore
alias sound-slot-0 snd-card-0

# card #1
alias sound-service-0-0 snd-mixer-oss
alias sound-service-0-1 snd-seq-oss
alias sound-service-0-3 snd-pcm-oss
alias sound-service-0-8 snd-seq-oss
alias sound-service-0-12 snd-pcm-oss

Anyone have any ideas?
