Roon 1.8 version Software Communications

Roon version 1.8 has communication problems with an Oppo 205 when using an Optical Rendu over connected too USB of the Oppo. Having not listen in a while was force to load 1.8 :pensive: After installing 1.8 on my IPAD went to stream some, however as soon as I connected it Roon on the tablet stopped. After going through numerous tests the problem only happen when tried to play audio through the USB Audio input of the Oppo 205, the Ethernet works fine. When the Oppo interface was enable Roon stop playing every time I went through multiple setting nothing fixed it. However, I did got Roon playing through the Oppo USB by pulling the Ethernet cable from the Oppo.

The first thing they should have tested were different interface with this software.
Roon skip a lot of corners horrid instructions. I waisted a lot of time with there product and I really sorry that I have equipment such as the Rendu and the Sonic Transporter that or designed to work with Doom.

Is the Optical Rendu hardware supported by Oppo?

Curious if something is getting lost in the connection.

The Rendu support the USB standard as does the Oppo does. I have run many version of Roon with that combination and it’s worked fine till 1.8. The facts are the majority of streaming DAC’s use the USB Interface for streaming. I not sure how Roon treats the USB INTERFACE that the issue as the Oppo is defined in the Roon configurations. You have to have a analyzer to know how their hand shake is working.

Frustrating for sure. Give ‘em a couple of weeks to sort things out. These big releases have required some clean up in the past; I’m sure this one is no different.

I just updated the 1.8 firmware to make sure it worked. Seems to be operating correctly in my setup. Haven’t used it except to system check it. Using other music gear / software.

Hi @James_Wilson1

Thanks for the details here. Just to confirm, if you remove the Optical Rendu from the equation and just connect the Oppo to the Core machine directly is there any change?

Can you give us some details about your networking and Core machine?


While Roon is running on my tablet I go to the Oppo and set the interface to USB at the point the music playing on Roon stop and message it has lost connection. The Oppo will not stay connected to the USB but Roon will staring again when I enable the music… PULLING the ETHERNET CABLE and the Connection to the USB will play. This all worked fine before.

I cannot do any testing on as we are having severe weather and rolling blackout.


If I disconnect the Rendu it will play via the Ethernet it works with Roon. If I disconnect the Ethernet Roon will use the USB interface.

I will check it again this evening, if he power stays on we are having rolling blackout because of the serious weather we’re having in North Texas.
