I need to fish some speaker wire through my ceiling downstairs to the lower part of the adjacent exterior wall. To compound the problem, the ceiling joists run perpendicular to the direction I need to run the cable. I have a feeling I already know the answer to this, but is there any way other than cutting several holes in the ceiling to drill through the joists? The run is about 10 feet.
EDIT
The ceiling is a smooth drywall ceiling. The joists are I joists.
