Bug Description
On Lenovo L450 laptop, when I boot the PC with headphones attached, then the sound via headphones will work, but there will be no sound from internal speakers when headphones are detached.
I tested this couple of times and the problem is always reproduced. This is the procedure A:
1. When the problem is not present, sound is present in laptop's speakers, connect the headphones
2. initiate reboot
3. once booted, initiate playing of some audio and check the sound from headphones - it will work OK
4. disconnect the headphones - there is no sound from internal speakers
Procedure B:
1. turn off the laptop (power off)
2. connect the headphones to the laptop
3. power on the laptop and boot into Ubuntu 15.10
4. once booted, initiate playing of some audio and check the sound from headphones - it will work OK
5. disconnect the headphones - there is no sound from internal speakers
