I've been looking for answers to an audio issue that started 5 months ago, shortly after replacing my old receiver and I've found nothing in that time. I hope someone can help me by me posting my issues specifically. Let me know if I can explain anything further.
Setup: Sony TV KDL55W800B, Mac Mini (2011), ATV4, Oppo Bluray BDP-83, PS4, all connected to Marantz receiver SR6010, via HDMI. Issues started when I replaced my old Marantz SR7002 with the SR6010 in January.
Issue: Audio playback through the Mac mini (my media centre) was distorting sound intermittently. I'd be watching a show and every second sentence would drop out, or the sound would distort entirely, and then come back, completely at random. I initially assumed it was a VLC playback issue thru the Mac mini. I bought an Apple TV (Gen 4) to remove VLC playback from my setup in February & playback was fine, but amp started switching to AirPlay and zero'ing volume randomly. (Turned off ATV auto remote & devices, issue persists). Bluray & ATV started replicating the initial sound issue described by April. Volume now also seems to increase and decrease during playback randomly. These same issues are now witnessed using VLC, QuickTime, Plex (Mac mini), various blurays (Oppo & PS4), iView, Plex, Netflix, Stan (ATV). There's no consistency to when the sound will fail, or on which device. The only common element in the Marantz. I don't know the correct word but the speaking appears to get pitchy right before the problem hits, it's the first sign that the audio is about to malfunction.
I also have an issue that the receiver display will state 'muted' + mute icon on tv screen, yet I'll have full sound that I can adjust (also random & cannot replicate at will). I also find that when the receiver is turned off & the TV remains on that devices plugged into the receiver will sometimes still work through tv alone (audio & display).
- Introduced ATV & removed VLC use (problem now occurs when using ATV).
- Replaced all HDMI cables (no result).
- Turned off ATV auto remote control (as per idownloadblog article) (no result).
- Disconnected & reset receiver from factory settings, problem free for 4 weeks before issues resumed (in May 2016). Disconnecting power fixes issues from 30mins, up to 3 days before recommencing at random times, on any or all devices through receiver (results vary, problem remains)
- Turned off Eco mode on receiver (no result).
Any ideas besides returning to the store and hoping they can replicate these faults? I have captured some footage, but it seems the surest way to fix the problem is to try & record the fault with my iPhone.
If no one has said so, welcome to AVS!
Can you advise your speaker setup? Is it 5.1/7.1 and do you plan to go to Atmos/DTS:X/Auro3D object audio? Please take a look at the basic 5.1 setup in the picture below (it's also included in your Marantz SR-6010 owner's manual).
5.1 speaker configuration:
Did you carry out the Audyssey auto-calibration with the supplied mic that came with the SR-6010? If so, what are the results? When carrying out the auto-calibration, were all the speakers able to "see" the mic and the angles from each speaker to the Main Listening Position (MLP) are that shown in picture above? Using a mic boom stand or tripod for the auto-calibration will give more consistent and repeatable results, but one can also use the rocket ship cardboard that came with your receiver as a start.
What is the make and model number of the speakers you're using? Are you using a sub?
What is the listening room dimensions? Front to back, side to side and floor to ceiling? How far away are the speakers from the room boundaries?
Is your SR-6010 brand new or a 2nd hand unit (i.e re-furbished). The warranty will tell you as a brand new unit comes with a 3-year warranty from an authorized dealer while the 2nd hand only gets a single year. If you did get a 2nd hand unit, carry out multiple factory resets (jdsmoothie recommends 4x to 5x) to clear the internal memory. Please note that getting a 2nd hand unit means taking on some risk and at least one 2016 Marantz owner had to go through 3 re-furbished units, before being satisfied with his 4th unit.
Use the Oppo universal blu-ray player BDP-83 as the test source, the Oppo will send both accurate video and sound signals to the SR-6010. Ensure that bit-streaming is enabled on the Oppo with secondary audio set to OFF. If the Oppo has deep color, also turn it OFF. Grab a calibration disc such as the Spears & Munsil HD Benchmark and Calibration Disc 2nd Edition
and a hand held SPL meter
with C weighting. With the volume at 0dB (80 on the absolute scale) on the SR-6010, play the 75dB test tones for each of the speaker channels on the calibration disc. At the MLP and with the SPL meter held at ear height, are you getting 75dB? There will be some slight errors depending on the accuracy of the hand held meter, but it shouldn't be more than +/-3dB.
Once you've got the Oppo and SR-6010 setup correctly, test with the PS4. Are the results the same? It should be, if not then there some settings on the PS4 that needs to be adjusted.
