[mac mini] can't select audio output if using ACD and speakers

[macchiato2009]

Hi there

i have noticed a strange thing

i'm using my mac mini with the ACD 24" and i get the sound from the screen because it is "very slightly bettter" than the speaker of the mac mini (even if both are quite disappointing)

anyway,

when i connected external speakers on the jack of the mini, it is simply impossible even with the soft soundsource to switch audio outputs on the fly

external speakers seem to have the priority over other outputs

is there a way to get through it ?


thx
