Description of Issue

Roon does not show Audio USB connected DAC SMSL SU9 Pro

Do you need to install the drivers?

You could try a different USB cable and/or USB port

Thanks Jeff,
I now installed ASIO driver to my Windows PC, and SMSL shows up on this PC

As you can see, device initialization failed. Tried a restart- same result. The Roon server on NAS is connected to the SMSL via NAS USB:

I hope that it is intended that Roon can be controlled from both PC, tablet and mobile phone. With the option to choose audio output from all of these??

To be clear, you are using the laptop for control but your DAC is plugged direct into the QNAP NAS which is the Roon core?

Yes, that is right

And did you enable your core under audio device as output?

Like my Cambridge Cxn V2 streamer is able to use Raat, chromecast and apple AirPlay with Roon. But I would have to enable all options in roon first.

So you need to check if your core is enabled as endpoint.

Settings - audio - connected to core

As you can se from 2. above screenshot, Roon server is connected to SMSL USB AUDIO. But it is not possible to initialize this USB DAC, see 3. picture above

Wouldn’t this work only with roon ready devices anyway? Everything else will just show up as usb audio device (like my smsl D300)

Installing drivers on your pc remote are not going to make it work if it’s attached to a QNAP core. It’s just installing driver for that pc only . The problem you have is usb audio on the QNAP likely a kernel issue with the DAC and what Linux kernel QNAP are using. Your better using a bridge of some kind to the SMSL such as another pc or raspberry pi if you have one or a low cost streamer.

As above what matters is the relationship between the DAC and the device it is plugged into. I think QNAP ended that capability a while back. I may be wrong but I think you have to have a bridge device for Roon with the core on a QNAP NAS.

Finally! Retrieved files from Release ffmpeg b5.0.1 binaries · eugeneware/ffmpeg-static · GitHub. Copied in linux-x64, linux-x64.gz to the RoonOnNAS/bin folder. Now we are up and running. Thanks for all the contributions!
