\"sound<\/a><\/p>\n

I rarely use headphones on my Ubuntu laptop. But when I plugged in ones today, sound was coming from both headphones and speakers in Ubuntu 14.04.<\/p>\n

This is a very old bug<\/a> with alsamixer. If you happen to have this issue on Ubuntu 14.04, you may try below steps to fix it:<\/p>\n

1<\/b>. Launch a terminal window from the Dash, App launcher, or via Ctrl+Alt+T shortcut key. When it opens, run below command and hit enter:<\/p>\n

alsamixer<\/pre>\n
When you see following screen, use Left\/Right arrow key to navigate and choose Auto-Mute<\/b>, then enable it via Up\/Down arrow key.<\/p>\n
\"alsamixer\"<\/a><\/p>\n
2.<\/b> If it does not work, try GNOME ALSA Mixer<\/b> which can be installed from Ubuntu Software Center or by running below command in terminal:<\/p>\n
sudo apt-get install gnome-alsamixer<\/pre>\n
Then start it from the Dash or via gnome-alsamixer<\/code> command and enable Auto-Mute Mode<\/b><\/p>\n
\"gnome-alsamixer\"<\/a><\/p>\n
3.<\/b> Does not work? Well, here is how to install the latest ALSA driver for a “HDA Intel” sound card in Ubuntu 14.04, which fixed the issue for me.<\/p>\n
First make sure you have dkms<\/code> package installed.  Install it either from Ubuntu Software Center or via below command in terminal:<\/p>\n
sudo apt-get install dkms<\/pre>\n
Then select download the latest ALSA driver from THIS PAGE<\/a>.<\/p>\n
Depends on your Kernel version, check it out via uname -r<\/code> command, <\/p>\n
\"check-kernel\"<\/a><\/p>\n
select download:<\/p>\n
