Ubuntu – No sound from line-in


I have two computers that I want to have coming through the same speakers, I bought a cable, which I connected from the headphone jack on the one computer to the line-in jack on the other.

I know sound is coming out of the headphone jack (confirmed by using headphones). But when I plug the cord into the line-in, I can't get it to output the signal that's coming in on line-in.

  • You may be able to redirect the line-in to your sound card output by using gnome-alsamixer (sudo apt-get install gnome-alsamixer in case you don't have it).

    Just enable the Line option and you should get the input sound redirected to your sound card's output.

    I kind of have the same problem, but instead of redirecting to the sound card's output, I'd like to redirect to my USB headphone's output (which contains a separate sound card).
