Marantz Cinema 70s: route a direct HDMI player to receiver speakers. Check prerequisites and the actual response before reporting an outcome.
Manufacturer-documented Reviewed 2026-11-09 · Revision 1
Follow these checks in Audio Fix →When this guide applies
Direct HDMI source, receiver on, HDMI Control already confirmed off.
Connection scope: HDMI / ARC / eARC audio. Symptom: Sound goes to the wrong output.
This is a documented check, not a diagnosis of your equipment. The model name does not confirm the selected input, mode, software or connected partner.
If your exact model or a required setting is unknown, use the “I don’t know” branch below. Do not apply a similarly named model’s instructions.
Checks and possible outcomes
Start at step-0. Follow the link that matches what you actually observe. Alternative branches are not a single sequence of actions.
step-0
Is this a player connected directly to a receiver HDMI input?
This is not the TV ARC/eARC return path.
Look for: Confirm the actual prerequisite or observation. Unknown stops safely.
- If Yes / check completed → Is receiver HDMI Control confirmed off?
- If No / cannot confirm → Keep these observations for official support
- If I do not know / cannot check → A required fact is unknown

step-1
Is receiver HDMI Control confirmed off?
When active, TV audio settings take priority. Do not blindly change HDMI Control as part of this routing flow.
Look for: Confirm the actual prerequisite or observation. Unknown stops safely.
- If Yes / check completed → Do you want HDMI sound from receiver speakers rather than the TV?
- If No / cannot confirm → Keep these observations for official support
- If I do not know / cannot check → A required fact is unknown

step-2
Do you want HDMI sound from receiver speakers rather than the TV?
Changing the destination may stop TV-speaker playback. Keep volume low before the handoff.
Look for: Confirm the actual prerequisite or observation. Unknown stops safely.
- If Yes / check completed → Set Video > HDMI Setup > HDMI Audio Out to AVR
- If No / cannot confirm → Keep these observations for official support
- If I do not know / cannot check → A required fact is unknown

step-3
Set Video > HDMI Setup > HDMI Audio Out to AVR
Use the known named destination, not a toggle. Retain the previous setting for restoration.
Look for: Perform only the stated operation, then confirm whether it could be completed.
- If Yes / check completed → Does the intended HDMI source now use the receiver speakers?
- If No / cannot confirm → Keep these observations for official support
- If I do not know / cannot check → A required fact is unknown

step-4
Does the intended HDMI source now use the receiver speakers?
If not, record source, input and destination; do not assume the player supports an unverified audio format.
Look for: Confirm the actual prerequisite or observation. Unknown stops safely.
