There is no sound in any computer game.(including Alien Arena given in July issue) However there is no problem playing audio/video files in xine, Kaffeine,Amarok,RealPlayer etc. I am using SuSE Linux 10.1 with win32codec installed. Sound is onboard Intel 915 GAV motherboard and P4 2.8 GHz. Please help so that we can enjoy computer games in Linux too.
