Sonore microRendu with Benchmark DAC2 and ROON READY [Resolved]

I have 2 DACs. An Emotiva XDR-1 in the office. I setup Sonore microRendu on my network and connected to the DAC. Started up ROON and configured the microRendu as a NETWORK device. Pressed play and all worked fine.

I then moved to my living room and added the microRendu to my Benchmark DAC2. Started up ROON and I could not get ROON to play on the Benchmark. I do know the Benchmark is supported by Sonore. I can see the microRendu on the home network. Roon just keeps skipping the tracks very quickly when I queue up something to play. I get no sound out of the stereo.

Has anybody got the following combo to play music:
Benchmark DAC2
Sonore microRendu
ROON Ready
ROON

If so, what settings do you have to make this work?

Thanks

Haven’t got the gear, but the first thing I’d suggest is checking that the Roon Ready app in the Sonore software is configured to accept DoP, which the Benchmark needs.

I believe I have DoP configured in the only place that accepted that choice in the ROON READY software.

I have a diagnostic dump from the microRendu software and I believe the issue can be tied the following labelled exception, RAAT__OUTPUT_PLUGIN_STATUS_FORMAT_NOT_S UPPORTED

no setup

Try this:

Go to Apps and select Software Manager
Now select Update
Wait for “Back to main menu” to appear at the bottom of the screen and ignore any Complete notices.

Go to Apps / DAC Diagnostics and make sure the DAC is active.

Go to Settings / RoonReady and make sure all the settings are correct. Set the volume control to None (100%). Then press Save. Pressing Save rebuilds the Roon config file and restarts the RoonReady endpoint. This is important!

Go into the Roon user interface and make sure the microRendu is selected.

Play a track and look in the Apps / DAC Diagnostics to make sure the DAC is actually playing.

I tried this steps as exactly as outlined, once with the Edge Browser and the other time with Google Chrome. Both times ROON fails to play. ROON has the microRendo as the ZONE to output the music. I mentioned before that this setup worked when I used my Emotiva DAC XDR-1 with the microRendu as a Networked ROON ready device. The microRendu connected to the Benchmark is not working.

The Benchmark is located physically in a different room than the Emotica. However, both were hardwired by Ethernet when I tested them. The Benchmark actually has a shorter network path. The fact that the ROON server can see the microREndu as a Networked endpoint makes me think the network is fine.

Anybody here got the microRendu to work with the Benchmark DAC2 and ROON? I would have figured this was a fairly common configuration.

To clear up any ambiguity I took my Benchmark DAC2 and moved it to the office room where the Emotiva lives. I disconnected the Emotiva from the speakers and hooked up the DAC2. I used the same wires that I used in the other room. No success.

I then removed the USB wire from the DAC2 and connected the Emotiva with the wires. ROON found the network endpoint, as was the case with the Benchmark. However, as was the case in the past with the Emotiva, ROON played via the microRendu flawlessly.

So there must be some issue with the microRendu or Roon Ready interface and the DAC2. I would be great if either one of Sonare and/or ROON READY can test this configuration and report back what happened.

I am using a WIndows 10 machine as my ROON server.

Are you getting a signal lock on the DAC when you try to play something? What volume setting did you select in Settings / Roon Ready? Post an image of the settings in Roon.

When ROON is not playing anything the DAC Diagnostics looks like the following:

The next image is the DAC Diagnostics when ROON is playing an album. ROON flies through the tracks spending 1 second or less on each track.

The next image is the ROON READY Settings used with the DAC Diagnostics images from above (previous reply).

The next image is the screen shot of my DAC2 with what I believe is a signal lock with the microRendu. ROON is not playing in this shot.

Some other ROON READY settings I tried (unsuccessful).

Last Post on this question asking for screen shots. I decided to disconnect the microRendu and connect my DAC2 by USB directly to the ROON Server Windows 10 PC. I then enabled the Benchmark DAC2 USB Audio 1.0 driver. Started up the same album on ROON as before and the DAC2 was playing music through it (it worked). However, the lights on the DAC2 had an additional light come on (maybe signal lock indication). The additional light is the 24 bit indicator for the input.

A couple of things:

  1. You have the DAC in USB 1.0 mode. Look in the manual on how to change it to USB 2.0. In this mode the most you would get is 96K playback and no DSD support.
  2. You need to set the microRendu to DoP in order to support DSD.

Thanks, that was the problem. Now the microRendu is connected and playing the DAC2 perfectly.

If anyone is interested the following text describes how to set the DAC2 to USB 2.0 mode:

Caution: Close all USB audio playback applications before changing the USB MODE. If an audio application is playing while the USB MODE is changed, the audio application may freeze.

Note: The computer and DAC2 must be connected and both must be on before the USB MODE can be changed.

To change the USB MODE, select the USB(U) input on DAC2 and then press and hold the USB button on the remote control for 3 seconds. If a remote control is not available, simultaneously press and hold both INPUT buttons on the front panel for 3 seconds.

After holding the button(s) for 3 seconds, either the 4X lamp or the 2X lamp will flash once indicating the new USB MODE. A flash of the 4X lamp indicates that the unit is now in USB Audio 2.0 mode. A flash of the 2X lamp indicates that the unit is now in USB Audio 1.1 mode.

Tip:The 4X or 2X lamp will flash once every time the USB input is selected. This flash provides a convenient indication of the current USB MODE. Tip:Avoid any unnecessary switching between USB MODES. Rapid switching between modes can confuse some operating systems.
