    I'm going out on a limb here and suggesting we start a list of equipment that has incompatible operation over HDMI with the Eversolo DMP-A6. To add context to the discussion I suggest posters note what version of software they are running on the DMP-A6 as the issues some users are having may disappear as updates to the product become available.

    Sony STR-DA5600ES:
    • No native 2ch or multichannel DSD support via HDMI.
    • No multichannel support for PCM via HDMI.
    • 2 channel hi-res PCM files get down-sampled to 48kHz no matter what the native sampling rate is, however if the sampling rate is 44.1kHz it is correctly reported and outputted as 44.1kHz and 48kHz sampling is correctly reported and outputted as 48kHz. Everything else isn't.
    • DMP-A6: V1.1.75; V1.1.80

    Le DMP-A6 ne fonctionne pas du tout avec le DAC Singxer SD-1, alors que je peux brancher ce que je veux sur ce DAC, je trouve cela nul. Au bout de trois mois la sortie USB s'est mise à distorsionner par intermittence, j'ai été obligé de renvoyer le DMP-A6 en réparation. Je suis très déçu par cet appareil.

    AVR Onkyo TX-NR5007 does not see DSD 5.1 signal. When switching to DSD 2.0, the sound passes through. I bought the A6 specifically for DSD 5.1 playback. I can't use it. The old Pioner BDP-450 easily transfers DSD 5.1 to Onkyo.

    I tried also with a Sony STR-DN1080 receiver. Under V1.2.30 firmware I can get multichannel PCM and stereo DSD64 to decode. Sadly even though the receiver's display indicates it is receiving DSD5.1 the receiver does not reproduce any audio from any channel. :( The receiver works perfectly with other multichannel sources over HDMI like my Sony SCD-XA5400ES SACD player as well as other universal SACD capable players. Just not with the eversolo DMP-A6.

    I think my only option now is to purchase another DSD capable receiver that will work with the DMP-A6 if I want to still play multichannel DSD.

    Buying another receiver is not a solution. We need to wait for a response from A6 technical support. We need to understand the reasons. Perhaps the problem can be solved in new A6 firmware. I have an Onkyo top AVR and it works great with DSD 5.1. But the receiver does not see the signal from the A6.

    On Marantz Cinema 50 works flawlessly both DSD streams, stereo and multichannel.

    I agree, but after owning my A6 for quite some time now and undergoing many firmware upgrades I'm no closer to DSD 5.1 from my A6 with any of the receivers I own. Even though all of these receivers handle multichannel PCM very well, DoP from the A6 has stuttering audio via HDMI. Once again it's a mystery that doesn't seem to have a resolution. Another point which doesn't strike confidence is that in the DMP-A8, eversolo have dropped multichannel support completely, replacing the output HDMI connector with I2S support only.

    There is a guess. From the HDMI output of the AVR, send a video signal to the TV. Perhaps DSD 5.1 will work as an audio track for video

    Understanding your frustration, but... has the A6 ever been advertised as capable of routing MCh DSD over HDMI?
    Leave aside that routing audio as-is should not be a big thing to do, still if not advertised, IMO, should not be kept as a "reason to buy"...
    Totally different from, say, AirPlay 2, which indeed WAS (mistakenly, or too-enthusiastically) advertised as a feature, and lately fell (as of now).

    Strange text. The manufacturer Eversolo A6 has always advertised and is now advertising in the company store that the A6 is a DSD multichannel player. Therefore, our desire to ask for technical support is completely legitimate. This feature was key for me when deciding to purchase.

    The blue screen on the AVR TV did not help. In this mode, the AVR does not see the DSD from the A6 at all. Help is needed.

    Don't know how you can draw conclusions but here you go.

    Also wouldn't make sense to have options for it in the settings if it was an "undocumented" feature

    You may be right... As-is, it's misleading... it is obvious that multichannel D2P is to be supported; it's not so clear whether also DSD Native is.
    Had it been written "2x DOH chips, support HDMI multichannel output (up to 5.1) in both DSD Native and D2P" would have made it more clear.

    What is misleading? Not a native English speaker but it looks pretty clear to me....2x DOH cips "comma" support (the chips) HDMI DSD Native AND D2P multi-channel output (up to 5.1). "And" is key ;)....meaning it does both

    yes. being multichannel and adjective immediately reconducible to D2P, and not so to DSD Native. That's the caveat.
     
  16. JamOne

    JamOne Active Member

    Yes, and following your logic DSD Native is immediately attributable to HDMI, the D2P is left hanging out alone without knowing what output is referred to :D.....it's called contextualization ;).

    But hey, if you want to be right ...here you go, you are right :cool:

    Are you playing a local multichannel native DSD file through HDMI? Or are you getting the stream in from, say, the network, and routing it to HDMI?
    Asking, because a lot of people are complaining that "routing" the stream as-is should be easy to do (that is: it does not currently work), difference being, that it could indeed work if played by the A6 from a local file.

    I believe the multichannel and even stereo native DSD support is a HDMI handshaking issue between the DMP-A6 and certain (if not most) DSD compatible AVRs and here's why.

    I had the A6 connected via HDMI to a receiver that it would work with it playing MCH native DSD. It played the SACD ISO in multichannel perfectly as expected. Whilst the track was playing we disconnected the HDMI cable and plugged it into a HDMI port on an AVR which the A6 didn't previous work with. Low and behold the DSD light on that AVR illuminated and it played properly in MCH and showed DSD 6ch on the A6. However this was short lived joy because as soon as the track ended no more DSD MCH. The AVR reverted back to 2ch PCM and the display on the A6 now showed it now outputting 44.1kHz PCM. We were able to replicate this behaviour many times. The conclusion was the A6 negotiated a handshake with the first AVR at the beginning of the track and outputs a DSD stream via HDMI. When the cable was swapped over and the next track plays the A6 re-verifies the HDMI connection. If the DMP-A6 isn't getting the "right" response from the AVR it defaults to stereo 44.1kHz PCM. Why is it doing this? I don't know for sure, just my hunch it's a handshaking issue. My knowledge of HDMI in this context is limited. I could go out and spend thousands and purchase a HDMI analyser, learn how to use it and perhaps discover what's going on but given I rarely work on the high level diagnosis of HDMI devices I could not justify the expense of doing so just to prove to everolo something is amiss.

    Now some other members have also reported DSD via HDMI issues and have noticed certain situations where "handshaking" between the DMP-A6 and the AVR doesn't always work. citing that powering on the AVR before powering on the DMP-A6 seems to result in a more reliable communication between the two devices. I too have tried many combinations of which device is powered on first with the result is my two Sony AVRs (STR-DA5600ES and STR-DN1080) don't like working with the DMP-A6 despite working 100% perfectly with every other DSD source I have. Absolutely no issues with either AVR playing DSD via HDMI from my many other DSD capable players including the Sony SCD-XA5400ES, BDP-S370, BDP-S380, BDP-S5100 and the UBP-X800 as well as several other makes and models of universal DSD capable players to ensure it's not a Sony only compatibility issue with DSD via HDMI.

    For context I'm playing my DSD64 stereo and MCH files and SACD ISO files from the internal 4TB SSD. I've tried the same from a drive plugged into the USB ports on the rear of the DMP-A6 with the same results. I haven't tried playing back from my NAS but I suspect if it won't playback via it's internal SSD or via an external drive attached to a USB port the playback over the network from a NAS is less likely to work.

    Surely someone at eversolo tech support can explain this incompatibility issue?

    I play SACD iso 5.1 from Synology NAS over both NFS and SMB. AVR only sees DSD 2.0. There is only one attempt left: connect the AVR through a special HDMI splitter that separates video and audio streams. If this does not help, then i need help from Eversolo technical support.

    I am playing from internal SSD and i have no issue at all. I do need to turn on my AVR first otherwise, occasionally, the A6 doesn’t play at all through HDMI. It just “scans” very quickly through the track producing no sound. I have a Denon AVC 4700H, one of the frist production batch, later came a new production with a new HDMI board and a TI DAC after AKM factory burn.

    I don’t think it has anything to do with the expectation of the AVR to receive a video signal. An AVR is designed for both audio and video. One of the HDMI input is even called CD with defaulting with such preset. Like @Alan Rutlidge said, it must be an handshake issue.

    if i have time i can try indexing the library I have on the NAS and if anything behaves differently.
