I mean this has to be a flaw in; take my kernel 2.6.17-rc4 with Ben Collins 
5,8 toonie patch. This patch only let me output sound in a generic way ( and 
a long explenation...). Hence forth; the original kernelwork does not have 
the correct "thecorrectwhateveryoutrytoexplain" or am I missing a point here?

AND in the same time, Arts does this fuckup to, cuz whenever I use alsa 
directly with mplayer & vlc (since the movie was my only problem) I got this 
sound where I can actually hear what the acctors say.
Then momen arts (noatun with movie)  puts its sound throught it scrambles.
