Hey WiiM community,
Frustrated after a Black Friday buy gone wrong—hoping someone with a Marantz/Denon AVR (specifically NR1609) has seen this and can point me to a fix. Replacement arrives Saturday, but want to avoid round 2 of troubleshooting hell. App shows tracks playing (test tone, radio, Amazon Music HD/Ultra HD), volume at 100% fixed, but zero sound through my Klipsch RP-600M speakers. HEOS built-in works perfectly on the same Marantz chain, so AVR/DAC/speakers/cables are good.
Quick Setup:
WiiM Pro connected via Ethernet (Cat 6 direct to TP-Link Deco AX2000 node)—no Wi-Fi used, rock-solid stability.
  • Optical out (Monster TOSLINK, red light pulses visibly when unplugged) to NR1609's single OPT input (assigned/renamed to "STREAMER" source—see attached photo of input menu; no eARC TV conflict).
  • Fallback: RCA analog out to NR1609's CD input—same silence.
  • App: Latest WiiM Home (v4.8.x), checked for updates post-reset.
  • Goal: Bit-perfect Amazon HD/Ultra HD (up to 192kHz/24bit) via Marantz DAC.
Issue Details:
  • App queues test tone/radio/Amazon tracks ("playing" indicator), but Marantz front display stays blank—no "PCM" or sample rate signal.
  • During initial setup, test tone "plays" in app but no audible output or AVR detection—had to hit "Yes" to skip the verification loop ( "No" bounces back to bitrate menu endlessly).
  • Post-setup: App > Device > Test Audio (bypass Amazon)—still silent, no display change.
Steps Tried (All No Dice):
  1. App Tweaks: Audio Output > Optical selected > PCM format > Exclusive Mode ON > SPDIF Resolution at 48kHz/16bit (low-res handshake) > Volume Fixed at 100% (toggled off/on). Tried Auto/192kHz max too.
  2. Marantz Side: "STREAMER" input selected > Sound Mode: Pure Direct, Direct, or Stereo > Volume 40–50 > Mute off > Audyssey MultEQ XT disabled (Menu > Speakers > Audyssey > Off) > Power cycled AVR (unplug 2 mins to reset optical decoder).
  3. Analog Test: Switched to Line Out (2.0V max) > RCA to CD input > Same silence on test tone/Amazon tracks.
  4. Resets: Factory reset 2x (hold Play/Pause 10 sec on hardware—heard "Restore to factory settings" voice prompt, LED red+white flash) > Full re-setup each time > Same silent tone loop.
  5. Other Checks: Cable ends swapped/ports blown out (dust-free); no multi-room grouping; input re-assigned/renamed from "TV Audio" to avoid eARC eirdness.
WiiM support replied quickly but generically (asked about reset prompt—which I confirmed—and suggested Bluetooth/Wi-Fi tests, ignoring the wired Ethernet/optical focus). , but no beta firmware yet.

Anyone with NR1609 (or similar Marantz slimline) run WiiM Pro successfully? Is this the known AVR optical handshake bug (PCM not decoding stereo from WiiM)? Any firmware tweaks, app hacks, or Marantz menu buried setting I missed? Open to anything—tried everything short of RMA.

Thanks in advance—dying to ditch HEOS app suck for that full Amazon library bliss.

Attached: NR1609 Input Assign screenshot (OPT confirmed for STREAMER). Also tested to see if RCA works still same issue, silence change CD to analog 1 as my input.

Cheers,

Hi
It might be worth factory resetting the AVR and trying it with the default settings.

@Mr Ee, any thoughts?

@Wiimer - why are you picking on me?
Did that Marantz menu screenshot remind you of mine from my NR1510?
:ROFLMAO::ROFLMAO:

Welcome @bonkers. Apt name, I imagine this is driving you there.
It would seem unlikely that neither the analog nor optical out of the pro work, but I guess it could be faulty.
Hoping you'll humour us while we ask what might seem silly questions / question your technical capabilities...

Can you provide a picture of the back of the pro and avr?
i.e. are the connections actually in the right sockets?
Sounds like the optical one is in the pro's output as it's glowing red, and there's only one optical input on the avr, so that one is strange..
For analog, is it possible you've used the pro's line ins instead of outs?

Have you tried using coax out into the avr? Any old rca cable should do, even one half of the rca that came with the pro.

Can you provide a screenshot of the wiim app's "now playing" screen?
Just to confirm something is playing, what output is selected and volume.

How else do you use the avr (non hdmi)? Do you have any other source (e.g. cd player) to check that works?

Do you have anything else you can plug the pro into to test it?
e.g. a bluetooth speaker with a 3.5mm aux in? (Do you have an rca to 3.5mm cable?)

It's been a while since I hooked a wiim up to my nr1510.
Your menu screenshot looks ok, although you could assign analog 1 to Streamer too so that merely changing the pro's output auto switches the avr's input.

And just for kicks, try the wiim supplied optical cable.

Thank you all for your responses and help! Decide to package it up and send it back yesterday, should not have to spends hours trying to set it up maybe Black Friday bad bunch, getting a new one on Saturday and hopefully this one will work, thanks again everyone!
