Ubuntu – Sound plays from laptop speakers only even when headphones are connected

headphonesspeakers

I'm using a Dell Vostro 1014 laptop with Ubuntu 11.10. From the time I had Ubuntu 9.04, sound comes from the laptop speakers only even when I plug in earphones or external speakers. Also, if an external microphone plugged in, it does not work. Dell even replaced my motherboard to check for hardware issues but the problem persists. So it is definitely not a hardware issue. The sound plays perfectly through the headphones in the pre-boot diagnostics. So I figure, this must be a problem with Ubuntu not recognizing my sound card.

Please try to give a solution for this problem.

I had the same problem: I plug in headphones, and sound comes out of the headphones and my laptop speakers.

Here's how I fixed this problem:

Go to Sound Preferences [click on the Sound icon in the top-right, on the bottom of the menu, you'll see sound preferences]

Next, go to the Output tab.

Here, look at the bottom, where it says "Connector:"

I think mine was on "Analog Speakers" [or possibly "Analog Headphones"].

Change it to "Analog Output"

Please try to tell me if this solution fixes your problem.

Also, you can try alsamixer to manaully turn down the Speaker volume.
