Noise from right speaker when startup Eversolo DMP A6

hello forum,
I just bought a streamer (2nd hand) Eversolo DMP A6 and am encountering the following problem.
When I turn on the streamer, I get a lot of noise on the right channel (resembling a radio that is not tuned properly). I only have this on the streamer input. As soon as I choose a different digital input the problem goes away. As soon as I start streaming music the problem goes away.
I have tried everything: factory reset, power off, completely disconnected from power, the problem remains. Are there more people with the same problem? I am running the latest firmware 1.2.50

 

Reloading the FW might do it. A factory Reset is not really cleaning everything (as it should).

 

How…manual? And can this be a hardware error? (it is in only one Channel).

 

Traditionally the system start up order would be dac first then power amps last , and the reverse when you turn everything off.

Yes, and what can I do with this info?
The noice is also sometimes there when I switch from other digitaal input to streaming. It’s quite loud, like I said, like a mis-tuned old FM radio. And only in one Chanel.

 

Send it back.
Keith

 

I would be curious as well, how "Reloading the FW" should work!

I still find it hard to understand or accept, that Eversolo is not providing a full flash image for their players anywere. I have requested this form the internationan and the german support team through email several times with zero response. Nothing but ignorance.

Uploading a flash image cannot be that difficult. For the Zidoo Players there are even dedicated "How to flash your...." sections under the support website. But for Eversolo: Nothing:-(

Therefor @Nice Monkey : Any help that you can give on how to arrange a new, clean installation is highly appreciated!

 

Did not try but mostly the same FW can be reinstalled following the USB procedure. This even when downgrading is not allowed like with Eversolo.
The why of this and neither providing an emergency full image overwrite is unknown to me.

 

That is only possible if you can download the firmware, and that is the problem, you can not.

 

May i ask you, to use your connections to Eversolo/Zidoo as a well established and experienced Beta-Team Member to communicate the need for a full flash image to the manufacturer? Uploading a flash image to the already existing supports website shoud not be that difficult...
Thanks!!

I just did a "Re-installation" of the FW V. 1.2.50 per USB Update yesterday evening. But why the heck is everything still there (settings, library entries....) after the update?? Seems to me that neither a factory reset nor a re-installation of the FW cleans up all settings.

 

Where did you download the firmware?

 

I found the firmware om this side: https://www.mcbluna.net/wp/eversolo...ew/eversolo-dmp-a6-firmware-download/#v1.2.50 strange that Eversolo does not provide the firmware om there own site.
After the firmware update the problem stays. Next step is contact the dealer.

 

I did make an interesting discovery. When I change the digital filter, the noise is present in some settings and some not:

fast roll-off (linear) = there is noise
slow roll-off (linear) = no noise
fast roll-off (minimum) = there is noise
slow roll-off (minimum) = no noise
apodizing (linear) = there is noise
fast roll-off (hybrid) = no noise
brick wall (linear) = no noise

this looks like a hardware problem.

 

These filters are integral part of the Sabre DAC chip itself. Never could detect an audible difference myself changing these.

http://forum.zidoo.tv/index.php?threads/new-version-1-2-50-1-2-80-for-dmp-a6-dmp-a8-release.97683/

...should be the same like from the McBluna Website

 

...btw. Here is an instruction, how a REAL Reset with cleaning up of all data can be arranged. I have not tried this out yet...

I did this reset, still after reboot my Tidal account was not removed on the device. And it did not solve my noise problem.
But thanks for this info.
