This came with a kernel update 3.2.0-35 I always leave my headphones connected to the jacks (left side, mic=red, ears=black). I don't use the built-in speakers very often and don't unplug my headphones. I noticed something strange after latest package updates and restarting because there is now a light on the keyboard f11 / mute key showing the sounds is muted. This didn't happen before. If I unplug the headphones then the light goes out and it unmutes. I can hear sound through the laptop speakers. Both +/- volume buttons work and mute key work and the OSD displays correctly. When I reconnect the headphones the light comes on f11 mute key and the sound disappears. The OSD still shows the master volume as 100% I went into system setttings.... sound... changed the connector from Headphones to Speakers and it seems to fix the problem but this is not permanent, as I now have to do this after every reboot. It used to work perfectly well before Yesterday so is there a way I can get it back the way it was?
