Sound not coming from Harman/Kardon speakers

Hi,

Check with your System Maker's Support (Motherboard Maker for custom systems) their

on-line documentation and drivers, and ask in their forums about any known issues.  Or

with the actual audio/sound device makers if a separate card/device.

Check with Toshiba Support, their on-line documentation and drivers (to update or re-install),

and ask in their forums.
