Volume applet shows only "Master" in list

Bug #497002 reported by Darwin Survivor

Affects Status Importance Assigned to Milestone
Awn Extras

Bug Description

distribution: Archinux x64-64 (fully updated, not using testing)
awn version: avant-window-navigator-0.4-bzr 20091213-1 (from AUR)
applet version: awn-extras-bzr 20091213-1 (AUR)
window manager: openbox (standalone, no DE)
video-card: nvidia 9600M GT using "nvidia 190.42-1 driver"

The volume applet used to show all my channels in awn 0.3, now it only shows Master.

The applet is also causing problems with certain controls messing with other channels. Ex: sometimes muting "side" (which is my sub-woofer) will also mute Master.

When front and side are muted, the applet also shows Master as muted. Muting then unmuting Master does not fix this.

I usually have 4 volume applets running at a time.
-Front (main speakers)
-Side (sub-woofer)
-Surround (headphones)

As this affects a specific applet, as opposed to general behavior, it should have been filed in the awn-extras project. Moving...

Sorry, I didn't realise there were 2 different bug systems for awn and awn-extras. Thank you for moving it.

You say it only shows Master, but at the end of the description you say you have instances of them running using Front, Side, and Surround. So what is it?

Furthermore, have you installed pulseaudio?

Please show a screenshot of the preferences window with the Device combobox open, and maybe a screenshot with the Mixer track combobox open too.

Last thing I want you to do: open a terminal and type alsamixer (you can close that by pressing Esc key). If you have that program, then do this: deactivate all the volume applet instances, and leave only a volume applet with Side Then mute Side and check in alsamixer which channels get muted. This should only be Side.
Then the second experiment: leave volume applet with Side open and activate another that you should configure to use Master. Then toggle mute of Side and check what gets muted in alsamixer.

The mixer tracks are retrieved via GStreamer. In this case via pulsemixer. This is a thing of PulseAudio.

For anyone else experiencing this problem with pulseaudio:

- There is an open feature-request
- Remove "pulsemixer" from line 68 of /usr/(local/)share/avant-window-navigator/applets/volume-control/volume-control.py
-- this will cause the applet to fall back to alsamixer, giving it independant channel support
