Chords only play as one note? (NOT a voicing problem)

i recently installed Live 9 on my Sony Vaio, and i already have a fully working Live 9 on my Tower PC.
 
But on my Vaio, I can only play 1 note at a time on the keyboard OR in the chords programmed into the piano roll.

This seems to be instrument independent (native or VST), and it is definitely NOT a voicing/polyphony issue. i.e. i play 2 notes together, but only 1 note plays.

What could be the culprit? First I suspected something like the keyboard buffer, BUT it also happens when programming into the piano roll directly...

any native instrument or VST. however, e.g. kick and snare in a drum rack seem to play just fine together (which is a chord as well)

thanks for any input.
