Bug Description

This is a bit weird.... 12.04 on the SL410 from Lenovo (201011-6829). If I hit the volume buttons, volume is run up and down as it's supposed to be. However when I hit the mute button, I must then hit either Vol Up or Vol Down before the sound is actually muted.

To see this in action, load up a song (I used the one in the Ubuntu Showcase in /usr/share/example-content) and start playing it.

Turn the volume up and down using the volume keys. Then hit the mute key and note that nothing happens. Next, hit a volume key and note that now the sound mutes...

I'm migrating here from bug 1014744, I'll recap that one briefly.

The affected system is very similar (Lenovo SL510), so potentially the same innards, just a bigger frame to accomodate the 15-inch screen.

The behavior I see was originally reported as a failing Mute button, but upon closer inspection it's exactly as described by Jeff; mute works if a volume button is pressed after pressing mute (mute works like a "modifier" key).

The microphone mute button remains completely unresponsive, however.

I've confirmed this behavior on Oneiric (kernel 3.0.0-12.20), Precise (kernel 3.2) and latest mainline kernel (3.5-rc3 at the moment).

Since I tested mainline kernel I'll set this back to Confirmed.
