thanks for your response, brent. you spurred me on to try a bunch of different things, and though i'd be happy to answer your questions, after my findings, most of them are no longer necessary.

i tried a bunch of things with the audio cables, like using a rca cable instead of the hdmi to the projector, and that was all without luck. i eventually tried unplugging the projector from the ceiling outlet - instant silence. i tried plugging it into the wall in the room, buzzing came back; i tried plugging it into an outlet in a different room, buzzing came back; and i tried plugging it into the outlet in the closet right below where the sub is plugged in - beautiful silence.

i checked my breaker box and found that the closet was on a different circuit as the main room, which was on the same circuit as the rest of that floor. so apparently it works okay as long as the subwoofer is on the same circuit as the projector. "okay," i though, "then i'll keep the projector plugged into its ceiling outlet and plug the sub into the main room" (i was just plugging it into the closet out of convenience). with that option, i have a faint, but audible buzzing; much better than before, but not ideal. so now i'm back to plugging the projector into the closet, which will be some weird looking wiring, considering there'll be an empty outlet on the ceiling next to the projector and the power will be run back along the wall.

i assume i must resign myself to that setup, unless there are any other suggestions?

thanks again brent!
