Comment 55 for bug 337314

Hmmm... P. Dunbar, I agree with you. Listening more carefully [1] it seems like the center speaker is mapped to the right speaker (is there a center-speaker anyway?) and the sub-woofer isn't producing any sound. However, via headphones-plug the external sub-woofer plays the "bass" sound which is in the "sound test" video (link below).
