Posde: first of all i didn't know there was a deb until i started this thread and secondly i was troubleshooting and adding debug to squeezeslave. I will use the deb in the future when everything works. Maybe somebody can edit the wiki to say where you can find it?
The dmix device was the proposal of the guy that keeps up with squeezeslave himself, i had tried other devices but nothing worked. This asym device works for me.
aico, no need to reinstall your core, first of all make sure the usb card shows up in aplay -L, then make sure it shows up in squeezeslave -L and yes use the full path to squeezeslave so for me this was /usr/local/bin/squeezeslave -L
Also looks like you used my line from the wiki exactly, i don't know if device 4 is the correct one, again look with the -L option.
