View Full Version : [ubuntu] Audio low from external speakers

May 15th, 2012, 01:53 PM
Hello everyone, I would like to ask you a question.
I've just done a clean install of Ubuntu 12.04 on my iMac, and everything works as it should, except for magic mouse's gestures (but that's another matter) and the audio, in a very strage way.
If I play audio files without connecting the computer to the speakers of my hi-fi system, the volume is good, loud; but if I do connect the pc to the stereo, the volume is incredibly low, and I have to push it to the top to even hear music.
I use gnome3, and its mixer is set to the maximum; alsamixer is set to the max too. It may seem to be a problem of the hi-fi system, but it works fine and play audio loud from my windows laptop.
The hifi is connected to my computer (an iMac 27" bought in february, I repeat) via the "headphones" hole, with a 3.5mm cable. This problem is present even if I boot from Ubuntu livecd and I play audio from it.
So please give me some advices about what to do, and sorry for my not very good english :).
