** 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
