Questions and answers
No audio is coming through. How to address this?
The provided context does not contain specific information on fixing audio issues with the Optoma HD20 projector. However, to connect audio with the listed equipment:
1. The Optoma HD20 does not have built-in speakers, so audio must be routed separately.
2. Connect your source device (e.g., Blu-ray player, streaming device) to the Onkyo A-9050 amplifier using an appropriate audio cable (such as RCA or optical, if supported).
3. Connect the Polk speakers to the amplifier's speaker outputs.
4. Ensure the amplifier is set to the correct input source.
5. If using HDMI for video, check if the source device has an audio output that can be connected to the amplifier.
If there is no sound, verify cable connections, input settings, and volume levels on all devices.
