I have a Benq project connected with HDMI to my cable box. The sound and picture works great. I recently added Amazon Firestick and need to have my audio through my receiver. What cords can be utilized in the audio out to my receiver for sound?
The audio would best be connected to the receiver from the source. Connect the cable box and fire stick to the back of the audio receiver HDMI inputs. Then run one (1) HDMI (output) cable to the projector. That is the common setup for this scenario.
Please let us know if you have any questions.
