When i turned my Denon x1600h yesterday morning, there was no sound output / audio playing in the speakers. The video is playing well as always. The display on denon is working perfectly fine. Following are aspects i checked:
1. Checked my speaker wires. Found no issues. But still went ahead and redid my wiring. Still no sound.
2. Checked all my config.. couldn’t find any thing unusual
3. Changed the source - TV, Firestick, Airplay - no sound from any input. I initially thought it could be with my TV and tried playing via Airplay. Still no sound.
4. Removed the amp and played the content directly on TV. Audio playing well.
5. Did a factory reset (hold down power and channel - / +). Retried setting up the speakers from scratch. When it came to sound test, the Setup gets stuck on “playing sound on front left” - there is no sound. It doesnt let me choose any option on the screen except for back button to exit setup.
6. There is no indication of any power issues. Denon is turning on as usual, displays the green indicator. Front display is as bright as it always has been. Even the turn on click sounds are working as usual.
7. The display also shows what output it is playing (DDSur, Stereo, Dolby etc.) when i play video / content. But still no audio.

I am clueless as to what could be the possible problem is. I am planning to take it to authorised service Center. I spoke with my dealer and he said it is quite weird and he has not heard of this issue before. Any suggestions and help in this regard would be helpful.

Have you checked to see if there is a firmware update available that you can do? U said based on the content you are playing the unit display auto detects and shows DD or DTS too?

Yes. I did check that. The firmware is up to date. I have taken it to authorised service Center. They have said it will take 2 weeks before I can get it back. Hopefully this gets rectified.

If it's in warranty, they will get it fixed. All the best

Just check HDMI audio setting which should be amp and not TV or 'speaker B' is activated(even a headphone plugged in) before you go to service center..

Yes I also thought it could be this setting. I checked this before I took to service Center. There at service Center, before they took it in for service, they did all these basic checks just to ensure that the issue was not related to settings.
