[Bug 477226] Re: Sound simultaneously on headphones and speakers - Lenovo IdeaPad u350

[wagner]

Here is a more easy fix!!!

1) sudo apt-get install alsa-utils
2) amixer set 'Speaker',1 100% unmute

you can save this for every new session with:

1) sudo gedit /etc/rc.local
2) amixer set 'Speaker',1 100% unmute (write before: exit 0)
