For sure, this information is very helpful !!! => I've tried last year installing ET on Ubuntu 10.2, and this sound-problem took me long-time to solve and find the good info (yes i am a noob) But I remember I was encountering another "big" problem : the "keyboard-mapping" (sorry for inexact term) was wrong for many things: for vsays, for shortcuts, for binds etc .. so I was obliged to revert to micro$oft (for information, when Punkbuster was still alive, playing on Linux was my only way to avoid lags-peaks)
