    It was me, we did discuss about this. Interestingly even through my headphones I can pick this up. My ears are very sensitive to any sort of anomalies when it comes to electrical noises.

    Ok I tried last night using Poly in hotspot and Roon mode, but I am missing something I could not get Roon to see Poly's hotspot. They were effectively on two different networks. I am more than willing to do some experimentation to get this resolved, but I may need some direction.

    This will depend on where your Roon core is installed. So here at the office we run Roon on Windows laptops or on Apple Macbooks so we can take Roon to the shows we do around the world.

    Using this method all we do is connect our laptops to the WiFi from Poly and then open Roon and it will connect via Poly's own WiFi network and allow you to play. Of course using this then none of the streaming services
    will work but it will at least tell you whether you can play a local track stored on the computer.

    Gotcha, sorry, as I said, couldnt remember. I am fairly sensitive to it too I think, since it really does completely ruin the listening experience for me when I hear it and I heard it a lot with the mojo and poly. I also think its just a design "flaw" of the mojo and/or poly. They just likely aren't shielded the same way as other players or there is some other way the interference gets by that makes it audible. I toyed with the idea of getting a replacement, but already had multiple poly replacements and after more and more discussion, I came to the conclusion that its just the way they work, and that my headphones (and myself too) are just sensitive to it.

    Do you have any headphones that are better? Anything lower sensitivity to try it with? Just trying to see if you are getting it the same as me. Something to try it with and see if the sensitivity of your headphones is making the difference. Again, because that was it for me. I kinda jumped in blind with the iematch as I had no idea if it would help, but it definitely did, so just thought i would bring it back up and see if it could be a solution for you too.

    @Matt - I am having a strange issue with my Poly that has been successfully upgraded to 2.0. I hadn't used it in a week or so and the Poly battery went dead, After charging and turning on the Poly appears locked into the firmware update cycle with the alternating RGB Poly LED. Any thoughts on what could be causing this and how to restore to normal operation. GoFigure can find the Poly while it is in this state and is reporting FW V2.0 with no update available.

    The RGB cycling is normally during indexing the SD card.

    The Poly light flashes several times a second when indexing. If I remember rightly, it flashes quite a bit more slowly during fw update. Also Gofigure should report whether indexing is in progress under General Settings.

    Having the first deadlock state since 2.0.0 was installed. Happened just like the others before: switched on Hotspot mode in Gofigure, and the Poly never came back online.

    What's worse this time is that the Poly status LED is off, so it's much harder to check when the battery runs out, so I will have to keep connecting the charger to see if the light comes up.

    :triportsad:

    Have you contacted chord support? Or @Matt Bartlett

    Random brightness question for Matt or John at Chord,

    What is the battery drain difference between the lights full on or dimmed on the Mojo? I love seeing the colours blazing but the battery hoarded in me can't help but think I'm draining the battery much faster. Do you have an opinion on the drain?

    Also, I tend to use Mojo/Poly exclusively and one of my use cases is late night listening in bed. Even on low setting it still pretty bright. Is there any chance that the poly via settings in the iOS/Android app could be used to control Mojo colour balls? Or is that sort of comms between the two devices just not possible. Would be nice to switch the lights off whilst still using the Mojo/Poly.
     
  12. huangwan
    I will give this a try tonight

    Is this resolved yet? As others have said a fast cycling of colours indicates the SD card is being re-indexed. The firmware update is a very slow cycling of colours.
    You can test by removing your SD card before switching on. If the colour cycling stops then it is down to a database rebuild on your SD card.

    That's for letting me know. So far we haven't seen a repeat of this behavior since releasing V2.0 firmware as it has a fix to reset Poly. Out of interest was Poly on low battery when you switched hotspot mode on? Switching to hotspot mode takes more power from the battery so if it was low it might just run out of power and switch off. If your Poly isn't turning on now can you try this. Plug it into the charger. Wait 10s then unplug. Then immediately plug back in and wait 30s and then the charge light should come back on.

    Hi @Audiophiliate No dimming the lights makes no noticeable difference to the battery run time so you can continue to let them blaze if you want to happy in the knowledge that your battery will last just as long!

    Unfortunately no there is no communication over the USB connection between Mojo and Poly so it wouldn't be possible. I do like the idea of doing something like that but there are certainly many advantages to keep all the audio in Mojo and the communications and connectivity in Poly to avoid signal and power supply noise.
