Description of Issue

Dear Support Team,

one of my Roon endpoints is a digital audio player from Onkyo, the DP-X1. On this device I use the latest Roon App to play music from my Nucleus. Both from its built-in hard drive and via Qobuz. I listen via my Bowers & Wilkins P7 wired headphones.
My problem: Roon plays the music through this endpoint with crackles and small glitches. I don’t have these with any other endpoint. The DAP is very high quality and with the Qobuz app, for example, there is no such interference. Is this a known problem with this DAP, can I do something against it? My current solution is to use the Qobuz app, but it lacks the functionality of Roon…

Best regards

Move the onkyo temporarily to where you can connect it with a cable and see if the crackling goes away. This test will see if it is the WiFi that is the issue.

Thanks for the advice. Unfortunately, the Onkyo does not have the ability to connect it via Ethernet. It can only communicate on the network via wifi.

Does it have problems with all tracks?

Tracks streamed from the Nucleus’ internal hard drive cause fewer problems.
Many tracks streamed via the Qobuz interface experience clicks and interruptions/disturbances. I am currently testing it with Lana Del Rey’s new album (Blue Banisters), where it is particularly noticeable.
Addition: the wifi module on the Onkyo player is not the best, however, that is a fact.

Does no one have any ideas? This means then that the Roon app on Android 5.1.1 is not the optimal solution, I guess. I think I’ll install the USB Audio Player Pro as a test and stream Qobuz with it, in the hope that it works without interruptions and sound dropouts.

Hey @UliR we’re so sorry for the delay in our reply, please know it was not our intention. :pray:t3:

I wanted to check in to see if you’re still experiencing issues with the Onkyo DP-X1?

If so, I noticed that you are using a Fritzbox, as stated in our Networking Best Practices guide,

The FRITZ OS 7 update includes a feature called “Software Packet Acceleration” that can cause issues with remote connectivity. We recommend disabling this setting from the FRITZ GUI.

Could you please try changing this setting and see if there are any further issues? You can also change the DNS.

We have seen users have a better experience in the past if they change their Router’s DNS servers from the ISP provided ones to Cloudflare DNS, Quad9 or Google DNS. Can you please give this a try and let me know if it helps?

Thank you!

Hi Ashley, thanks for your advice. I disabled FRITZ OS “Software Packet Acceleration” and changed DNS to Quad9, but there are still issues with the Onkyo and the Roon app.
In between, a short, like static “crackling” can be heard, like dust on a record. Again and again. The sound is never really as clean as with any other WiFi endpoint. In addition, if you play the same track directly via the Qobuz app, everything sounds as it should, at least there are no dropouts / crackles…

@UliR Thanks so much for trying those steps - so sorry that they did not help.

How close is the Onkyo to your router? If you move it closer to the router, do you still experience the static during playback?

Are you using any DSP settings? Does disabling them result in any change?

Can you share a screenshot of the signal path when playing to this endpoint in Roon along with screenshots of Device Setup for this device?

Thank you! :pray:t3:

@ashley Thank you. No worries.

I am using the Onkyo as a mobile device, so I carry it around the house, but we have a very good Mesh WiFi, and the crackling is there even if I am sitting very close to the router.
No DSP settings in use. Should I try using it?

Attached some screens. Just for your information, the player is MQA capable, but I do not use MQA as I am a Qobuz guy. :slight_smile:

What I would like to add - it is a great pity that the Roon app apparently does not use the Dual DAC of my player, but outputs audio via the Android system. It would of course be a huge step forward if this could be changed. If it is possible at all…
