I can reproduce it easily with Ubuntu 13.04 (raring) with kernel 3.8.0-29-generic.
To make clarify what happens: There are 4 ways to get the current speaker mute status: 1. The mute led on the physical mute button. 2. The /proc/acpi/ibm/volume file 3. The icon (I'm currently using gnome-shell) 4. The PulseAudio Volume Control To mute/unmute there are 3 methods: a. The hardware mute button for the speaker. b. The slider for the volume icon in gnome-shell c. PulseAudio Volume Control If I use method a then all four statuses remain in sync. If I use method b or c to mute then 1 and 2 don't change. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/788540 Title: [Thinkpad T410s] Mute indicator gets out of sync To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/788540/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
