using speaker-test -c 2 -t wav -D pulse no sound in the subwoofer can be heard - its good (left / right internal speakers can be heard)

using speaker-test -c 6 -t wav -D pulse
from internal left speaker can be heard front- left / front-center
from internal right speaker can be heard front-right / front center
from subwoofer speaker rear-center (on console 5 - lfe is shown then)
