I have installed Unreal Tournament GOTY edition using the loki installer and the game work fine, with good frame rates but the sound is anoter story, as it doesn't work properly, is very bad and blurry.
¿ Does anyone has the same problem?
I had a problem similar to this on my laptop - I was getting no sound in UT at all. The solution I found was to disable the KDE sound server... granted, if you're not running KDE, this probably isn't of much help
What environment are you using? Are you using ALSA (which you probably are)?
If so, try putting aoss in front of the /path/to/ut like so:
I'm not sure what the name of your UT binary is or where it's stored, but give it a try with your path.
