The speakers are along the sides of the screen.
Yeah, it's bad design to rig so many cables into the monitor flap.
It's quite possible that something got snagged or just eventually
has been worked out of place or off the solder.
Try some headphones next time you're at work, at least then
you'll know if it's the card/drivers, or the speaker connection.
