Can't Get Speakers Sound With Optical Digital Connectiion And Hdmi Monitor Ou

Understanding the Problem:

You have a source device (like a TV, game console, etc.) connected to your Marantz NR1504 receiver via an optical digital audio cable.

You have your receiver connected to your HDMI monitor.

You're not getting any sound from your speakers.

Troubleshooting Steps:

Check Input Selection:

Make sure the correct input source is selected on the Marantz NR1504. The input should correspond to the optical port where you have your device connected (e.g., "Optical 1", "Optical 2"). You can usually cycle through inputs using the receiver's remote or front panel buttons.

Verify Source Device Settings:

Go into the audio settings of your source device (TV, game console, etc.).

Ensure the audio output is set to either "optical" or "digital".

Look for options like "PCM" or "Bitstream" and try experimenting with those settings.

Test the Optical Cable:

Swap the optical cable with a different one if possible. Faulty cables can cause issues.

Make sure the cable is fully inserted into both the source device and the receiver.

Check Marantz NR1504 Settings:

Go into the audio settings or speaker setup menu of your Marantz receiver.

Ensure the speakers are enabled and not muted.

Look for an "Input Assign" option and verify that the optical input is correctly assigned to the desired source.

HDMI Compatibility (ARC/eARC):

If your TV and receiver both support HDMI ARC (Audio Return Channel) or eARC (Enhanced Audio Return Channel), it sometimes overrides other audio connections. Check your TV's settings, the receiver's settings, and your HDMI cable to make sure you've configured this correctly for how you want things to work.

Additional Tips:

Consult the user manual for your Marantz NR1504, as it will have more specific instructions. You can usually find it on the Marantz website.

Try resetting both your Marantz NR1504 and your source device (a full power off/on cycle).

If you've tried all these steps and still have no sound, consider:

Testing different source devices: This will help narrow down if the problem is with the receiver or a specific device.

Contacting Marantz support: They may have additional troubleshooting steps or know of common issues with your receiver model.

1. Check Input Selection: Make sure that the input source on the Marantz NR1504 is correctly set to the optical digital input that you are using for your speakers. Use the remote control or front panel of the receiver to select the appropriate input source.

2. Verify Audio Settings: Access the audio settings menu on the Marantz NR1504 and confirm that the audio output is set to the optical digital connection for the input source you are using. Ensure that the receiver is configured to output audio through the optical digital connection to your speakers.

3. Check HDMI Settings: If the HDMI monitor is also connected to the Marantz NR1504, check the HDMI settings to ensure that the audio output is not being redirected to the HDMI connection instead of the optical digital connection.
