alsa amixer,alsamixer 'PCM on'?

[kcross]

I'm trying to use alsa-driver 0.9(?) downloaded from cvs.
I can't get any sound.Using YDL 2.2 on a PB G3 pismo.
I loaded driver,kernel,lib and utils.
Got alsamixer to load but Headphone,Line,CD,Mic and Auto Mut(e) don't 
slide.No PCM slider.
Other sliders work OK.

Executed:
'amixer set Master on' which produced:

Simple mixer control 'Master',0
  Capabilities: pvolume pswitch pswitch-joined cswitch cswitch-joined
  Playback channels: Front Left - Front Right
  Capture channels: Mono
  Limits: Playback 0 - 15
  Mono: Capture [off]
  Front Left: Playback 13 [87%] [on]
  Front Right: Playback 13 [87%] [on]

Executed:
amixer set PCM on: 
 Unable to find simple control 'PCM',0


Executed:
amixer set Master 75%:
Simple mixer control 'Master',0
  Capabilities: pvolume pswitch pswitch-joined cswitch cswitch-joined
  Playback channels: Front Left - Front Right
  Capture channels: Mono
  Limits: Playback 0 - 15
  Mono: Capture [off]
  Front Left: Playback 11 [73%] [on]
  Front Right: Playback 11 [73%] [on]

this moved the alsamixer and kmix(mixer00) volume sliders.

My modules.conf looks like this;I use the internal sound of the PowerBook,no 
pcmcia card:

# alias sound-slot-0 dmasound_pmac
# alias sound-slot-1 dmasound_pmac
# alias sound-service-0-0 dmasound_pmac
# alias sound-service-0-3 dmasound_pmac
# alias sound-service-1-0 dmasound_pmac


# ALSA portion
alias snd-card-0 snd-powermac
alias char-major-116 snd

# OSS/Free portion
alias sound-slot-0 snd-card-0
alias char-major-14 soundcore
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
# post-install snd-card-<powermac> /usr/sbin/alsactl restore



How do you get sound in alsa?

Best,
