I have an Infocus projector which has a 3.5mm audio out on it. I'm using a ChromeCast to deliver wireless A/V to the projector and then hoping to use a set of desktop 2.0 powered speakers to fill a classroom.
I'm finding that the 10w speakers are not quite loud enough off the projector. If I move the speakers to the casting laptop, then they are (amped?) enough to fill the room.
Is this because the projector doesn't power the speakers as the headphone jack off the laptop?
If yes, then what options do I have? Higher powered speakers? Some kind of in-line amp?
Or maybe redirecting audio from the "cast" to the laptop speakers? (Which I can't figure out how to do)
