** Description changed:

  Binary package hint: pulseaudio
  
+ [Problem]
+ Pulseaudio does not directly expose or allow adjustment of arbitrary mixers 
on the underlying card.
+ 
+ [Workaround]
+ a.  alsamixer -c 0   # where 0 is the hw id of the audio card
+ b.  alsamixer -Dhw:0  # ditto
+ c. with the gnome panel applet, if you right-click, choose preferences, and 
adjust the "Master" and "PCM" channels.
+ d.  shutdown pulseaudio, run alsamixer, and restart pulseaudio
+ 
+ `sudo alsactl store` may need to be run to make the changes persistent.
+ 
+ [Original Report]
  On HP 6730b, got no sound output from any application.
  
  Turns out that the PCM channel on the hardware mixer was set to zero /
  muted, and none of the standard knobs on the Gnome desktop could adjust
  it.
  
  Fixed on my box with "alsamixer -c 0", although I guess not every new
  user will immediately jump on that one.
  
- This is tested on Jaunty.
+ This is tested on Jaunty.  pulseaudio package (0.9.13-2ubuntu5)
+ 
+ Pulse audio doesn't appear to expose or allow adjustment of arbitrary
+ mixers on the underlying card.
+ 
+ Is there any mechanism by which pulseaudio can reliably expect the
+ various mixer channels it is relying on to be raised?

** Changed in: pulseaudio (Ubuntu)
       Status: Incomplete => Confirmed
