I have just bought a new ASUS u47vc computer. I have installed ubuntu 12.04 on it alongside windows 7 with no problems what so ever. Howevr, there is one issue that must be resolved. I can not get sound to come from the audio jack. The laptop's speakers work fine. It plays music and sound files fine with the internal speaks. However, when I plug in my headphones (or external speakers) the internal speakers mute (as they should) and nothing comes out of the headphones. Here are some outputs that might help: alsa information script: http://www.alsa-project.org/db/?f=82de5623cbdeeeae955cba02d7afe1a4b3fca965 Hope this problem can be fixed! Thank you in advance!!!
