sum problems with the soundcard and other stuff

hoi guys...

so i have some problems with me "soundcard" i got this thing when i bought the behringer xenyx 1204 FX :

and when i exit the sound thru it it's so quiet...then when i exit the sound thru the normal sound exit of my computah it's better but it saturates really quickly (when i play it thru the behringer mixer).

even friday when we used my behringer it saturated the whole sound so baddly.

i don't even know anymore what i'm asking here...

that soundcard is total crap right? but i've seen some people playing with such cards and they didn't have that problem...
