If you're facing audio output problems with your PulseAudio PAEXARC1 ARC Digital Audio Extender, here's a troubleshooting guide to help you resolve the issue:
-
Connection Verification: First, meticulously check all connections. Ensure the transmitter is securely linked to your audio source and the receiver is properly connected to your output device using the appropriate cables. A loose connection is a common culprit.
-
Power Check: Confirm that both the transmitter and receiver units are powered on. Verify that the power LED indicators on both units are illuminated, indicating they are receiving power from their USB adapters.
-
Source Audio Settings: Double-check the audio settings on your source device (like a TV or amplifier). Make sure it's configured to output audio through the ARC connection. Consult your device's manual for specific instructions on enabling ARC settings.
-
Display ARC Settings: If you're using ARC functionality, ensure your display device (e.g., TV) also has ARC enabled in its settings. The HDMI cable must be plugged into the ARC-designated port on your display.
-
Cat5e/6 Cable Inspection: If you are using the Cat5e/6 cable, verify it's in good condition and correctly connected to both the transmitter and the receiver. Ensure it's not damaged and properly seated in the ports.
-
ARC Backup Plan: If the HDMI ARC isn't functioning as expected, utilize the "ARC Backup Plan". Connect the optical audio output of your display to the SPDIF IN port on the transmitter and then through the HDMI OUT port on the receiver.
-
Contact Support: If these steps don't resolve the issue, it's best to contact Vanco Technical Support for further assistance. Have your part number, serial number, and any relevant invoice information ready to provide them with the necessary details.
