I\'ve the problem with all amarok versions (including 1.2.2)
that the xine plugin doesn\' t load.
Xine is properly installed and fully working.

[code:1]
amaroK: [Loader] Starting amarokapp..
amaroK: [Loader] Don\'t run gdb, valgrind, etc. against this binary! Use amarokapp.

I use gentoo, this may be the problem. Following some system information:

I had an similar issue today. After fiddling around with the settings for xine-1.0, I could persue AmaroK to play as usual when deactivating the xine-option to send changes to the hardware mixer...
