After many attempts and researches I found out that the sound
modules were disturbing the IrDA system (most likely an irq
conflict as Francesco suggested).

IrDA is now working fine without sound, I'll just have to find
the right order to start the things up and then I'm sure I'll
also have sound back working.

Thanks and regards,
Gianluca
