Hi Seth, I'm sorry for the delay in responding.
Long story short: I was confused during my debugging earlier this week when things appeared (sounded?) to work even though I wasn't able to get any of the keypresses to display any output via the means you mentioned. The issue is that the Mute button works, but only in that it mutes the laptop's speaker. It doesn't mute the headphone jack. Additionally, while the speaker is muted (but the headphone jack is still playing) the volume can be increased/decreased by the hotkeys. Additionally additionally, the sound applet displays "Mute" above the volume level. I'll work on getting you the actual output from the above debugging guides this weekend. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/810048 Title: Mute button does not work on Lenovo X200s To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/810048/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
