I used sabayon 10 and everything was OK. I reinstalled sabayon 11 and problem appeared. Instead of hmm and so on you should install sabayon 11 and you will see. I am experienced user of linux and I do not any nonsenses.
i had same problem in 11 that cant play mp3 files and i solved that with install gst plugins mad,but i type in rigo gst plugins mad and see two gst plugins mad one instaled and one didnt when install and second it worked
