[pascal lawrynowicz]

Hello,
Few times ago i ask this list about the terratec phase 26 usb device.
now i've got it and try to make it work with mandrake 10.1 community
And not everything go the right way. I cannot make it work properly. 
Maybe first i must tell that i'm a newbie and all knowledge about linux 
is hard to understand for me. So i need help and i hope you can help me.
Here is a little descrition of the problem :

mandrake 10.1 community / kernel : 2.6.8.1-10mdksmp SMP 686 gcc-3.4 /  
ALSA v 1.0.6 / kde desktop

The good :
-phase 26 usb seems to be recognize. I've got the the speaker at the 
bottom of my desk. Kmix give me : out = 1 fader, 1 pan and a green light 
; in = nothing
-kde configuration : config system > sound system activated ; test sound 
: ok i can hear something

The bad :
-no sound closing windows, clicking, mouse etc...
-cannot play a cd
-audacity : an error accurs during I/O audio initialisation. Cannot play 
or record audio. Error : host error (no dev inside)
-amarok : nothing to listen
-rosegarden cannot open
-xmms : nothing

-using aslamixer under su give :
