LiveWireBT: You are absolutely right - it is related to the indicator-applet/indicator-sound - removing the applet stops the main slider being altered when changing the balance.
Punting from pulseaudio -> indicator-sound. ** Package changed: pulseaudio (Ubuntu Lucid) => indicator-sound (Ubuntu Lucid) ** Summary changed: - Changing left/right balance in sound-preferences changes the output volume slider + Changing left/right balance in sound-preferences changes the output volume slider when indicator-applet is running ** Description changed: - Binary package hint: pulseaudio - Description of the problem: Moving the balance to the left in sound preferences is also causing the overall volume to become muted. Steps to reproduce: - 1. Start gnome-terminal . Run speaker-test . - 2. Run gnome-volume-control . - 3. Select the Output tab. - 4. Set the "Output volume" slider to 100%. - 5. Drag the Balance slider all the way to the left. + 1. Ensure indicator-applet is running and that the speaker icon is visible within it. + 2. Start gnome-terminal . Run speaker-test . + 3. Run gnome-volume-control . + 4. Select the Output tab. + 5. Set the "Output volume" slider to 100%. + 6. Drag the Balance slider all the way to the left. Expected result: Sound to only come out of the left speaker. Only the Balance slider should move. Actual result: Balance slider marker jumps back and forth while being dragged to the left. "Output volume" slider also moves to the left (seemingly all the way to 0). No sound is heard from speakers. How reproducible is this: It is reproducible every time. Version information: Ubuntu 10.04 alpha 3 gnome-media 2.29.91-0ubuntu1 pulseaudio 1:0.9.22~0.9.21+stable-queue-32-g8478-0ubuntu10 00:1b.0 Audio device [0403]: Intel Corporation 82801G (ICH7 Family) High Definition Audio Controller [8086:27d8] (rev 02) Additional Information: - This problem does not occur in Fedora 12. Possibly linked to Bug #413457 and Bug #525755 . + Pressing the right mouse button over the volume indicator applet and going to "Remove from Panel" (so step 1. no longer holds) resolves the issue. + This problem does not occur in Fedora 12. -- Changing left/right balance in sound-preferences changes the output volume slider when indicator-applet is running https://bugs.launchpad.net/bugs/532095 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
