I can reproduce it as well with some fiddling, but it happens very rarely.

I am not sure if this is the same bug, but it is very similar. I am using Hadry 8.04.1 and ALSA 1.0.15 I am experiencing this problem also but only with my usb headest. If I select the headset in System/Preferences/Sound I can control the volume with the multimedia keys but the left always drops to zero when I change the volume, Right channel reacts normally. This also happens when I have them selected in the panel Volume Control and try to adjust the volume with the mouse. This does not happen in the Pulse Audio Volume Control. When the sliders are out of lock from the above using the PA Volume Control locks the sliders back together and allows them to be adjusted in a normal fashion. This also does not happen with my C-Media 8768 PCI card or AC'97 on board sound or with any of the pulseaudio virtual devices. Is seems to be a strictly ALSA USB problem from here. -- gstreamer alsa mixer renders gnome volume controls useless https://bugs.launchpad.net/bugs/252237 You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gst-plugins-base0.10 in ubuntu. -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
