I connect the ZS to the Topping D90 DAC, and I usually play Tidal, and there is no problem at all with firmware 2.30.7. After I updated the firmware 2.31.7 (not beta) today, however, once I play songs with MQA 96kHz or above, the song cannot be played smoothly, and the display on the DAC keeps shuffling between 48kHz and 96kHz. And once I turned the dial wheel to Roon only mode, only COAX works, and there is no way to change the output to USB. Hope it can be fixed soon.
Paul itās a bargain, and the early problems are gone.
For Roon and HQP (which I think you use) itās a killer device at itās price point.
Sorry you have had to read so many of my wordās 
Bill I have Pi solutions as well (5 in the house) and they are great. Not a patch on the Stream though for SQ and besides some of the pain from testing thingās for this thread I have had almost no problem in the 11 months with the Stream running Roon (letās not talk about some of the other stuff).
For anyone happy with a Pi stick with it itās great.
Spockfish does Amazing work on Ropieee and I also like the HifiBerry OS deviceās I have with hatās.
RooExtend is also coming along nicely and I have two of those as well. Finally I have a DietPi which has been running for almost 4 years.
I asked the question of Roon about recertification and was told that Roon does not check or recertify future firmwareās. This was in relation to Cambridge Audio that broke it on the Evo range
It is disappointing to see them not fixing this obvious bug though.
Yes another person had this issue in the beta as well.
Hi, Michael, I have found the workaround.
Not only DSD cannot be played, but also volume is very low. So, I managed volume options like this.
Even if you want āNoneā in Volume Options, Mixed Type, you should first select āsoftwareā, and set default startup volume and max volume to 100, and save. Again, you should select āhardwareā and do the same thing. And, finally, you select ānoneā in volume options, mixed type, and save. Now, I can play both PCM and DSD at an appropriate (not unusually low) volume level!
Anyway, this 2.31.7 is not a stable firmware at all.

Hey guys, the USB mode is working after all!
- Set the dial on the back to mode 2.
- Open Roon, go to Audio settings, make sure the ZS is enabled. Itāll show S/PDIF.
- Click on the āDEVICE INFOā that appears at the top
- In the pop-up, select āConfigure deviceā
- A separate browser window will open up, allowing you to select output, volume and DSD settings. Change output to your DAC instead of S/PDIF, and voila!
Note that when doing this it also fixes the DSD options bug and the channel options disappearāeverything is working perfectly now!

Thanks for sharing that, it might helps others with the issue.

Had you already figured it out? I found out from a user on Head-Fi. I wasnāt even aware of that device info tab. Thereās even a link in that browser window that allows you to update the firmware!
I have not seen those on my system at all.
I was looking in Settings->Audio but I never saw a configure device, so I was going to the web page to do this.
I will have a look tonight and see if it is magically there now.

I did it right from Roon on my phone. Never caught it before, although itās been there all along, for Roon Ready devices, if you click on that ādevice infoā at the top of the audio settings for the ZS. Let me know if you get it to work. Have a great day!

It does work and sound quality seems slightly better than AIO.

I agree!
Now if I could only resolve the clipping Iām getting with DSD upscaling. If you enable headphone management but set the cutoff to zero, it maintains a bit perfect signal but the little signal star turns red when it clips. Doesnāt happen if I turn upsampling off. But I think this is a Roon issue, not a ZS one.
Anyway, glad one problem is solvedā¦
No worries. I bet you didnāt think this thread would be 1800+ posts in and still going.
Thanks for moderating it.

It was started to help me make the decision as to whether or not to buy one or not.
Good news now, plenty of help for the new community or Stream users

Iām not sure if this is old news, but the latest firmware also includes an auto firmware update tab that apparently allows the device to automatically install new firmwares, beta or otherwise, in the backgroundāeven when youāre device is set to mode 2. So this may obviate having to switch back and forthā¦
Also Michael, I was unaware that you were the OP for this thread. My sincere gratitude to you

Up and running with the new FW, but Iām not seeing the āconfigure deviceā option in Roon as shown in Stevenās post above. The Zen shows as Roon ready, and I can switch to USB in the iFi app if Im in AIO mode. If I turn the knob to Roon Exclusive (position 2), Roon shows as still playing, but there is no music and the iFi app wonāt connect. Thoughts? Thanks all for flagging this update.
Do you see it when you click on the ādevice infoā under Roon ready for the ZS? I didnāt realize that you could click that area.

That worked for me. Thank you for the tip.

Ah - thanks Marco. I did that and the IFi config page opened in a browser. It looked just like what I see in the iFi app, and my USB output was sellected. Iāll try the Roon Exclusive mode again a bit a later - I need to get some work done.
