This is an issue for me strictly with Native DSD. Was your test Native DSD. Thanks for testing.
Yes, it is with native DSD and a Holo May KTE DAC connected by usb
When connected by i2s I canāt play DSD at all.
Still figuring out why not
Same for me over i2s and DSD. I think it is a RS130 thing.
In Roon I can choose for DSD but then only see DSD64 greyed out so impossible to select anything and no sound however
Same for me. Not sure how to resolve.
Dsd64 should be doable in Roon with I2S and with native dsd, or DoP set on the Rose. That works for me, at least.
Well, glad Iām not the only one with this problem.
Letās wait for an answer from HiFi Rose
I2S should be able to do DSD in native mode but there also is no gear icon in the I2S section like in the usb to choose your DSD option
For those gear options, youāll need to select the gear symbol in the AES/coax/opt section.
Still, it would be better for Rose to either combine that section with I2S, or add a gear option in the I2S section. Besides that, that gear option needs to be expanded to make full use of I2S capabilities. Thus, putting I2S on par with USB, like it should.
No doubt, Roon will then also play flawlessly. 
Well, in this section Native DSD is selected but still no option to choose DSD options in Roon
I can select DSD but no sound is produced
Only way everything works is with USB
@ROSEHAN Can you give any advice in which settings we have to enable or disable to get i2s work with Roon on our RS130?
With USB everything works fine but when select upsampling in Roon with i2s connection there is no sound output
You are able to select DSD but in the DSD menu there is only DSD64 greyed out and you canāt open this select box
āDoctor, it hurts when I do that.ā
āThen, donāt do that.ā
Calling on @ROSEHAN to respond on mentioned issues.
Today Iāve been over at my PS Audio distributor to check on the I2S DSD256 issue. Well, we can exclude one device: itās not the dac. Using the Rose app, JRiver and an alternative streamer (the PS Audio Airlens, with JRiver and Roon), they all played DSD256 flawlessly. But playing these files through Roon through the Rose. over the I2S cable to the dac, there was that downsampling to DSD64 again!
Therefore, the issue lies with either Rose or Roon, or both. Given the RS130 is an upmarket product, this issue is something that needs to be fixed and in short term.
Could you please check if something has been overseen during the certification process and take appropriate steps to resolve this?
Kindly calling once more on @ROSEHAN (or perhaps @ROSELOA) to respond on above mentioned issues and preferably provide solutions.
In case you require more information, please let me know.
Thanks in advance!
BTW, as this issue may have to do how Roon and the RS130 interact, Iāve also posted the issue on Roon support under:
Currently awaiting response as wellā¦
Edit: on the Roon forum, someone suggested it will require a concise exchange of I2S specifications table with Roon software. If so, itās a simple case of a software update to sort this out. Iām not quite sure, if only on the side of Rose, or also on Roonās.
@ROSEHAN or @ROSELOA: can you please look into this and report back?
Edit 2 (another suggestion from the Roon forum):
Itās the manufacturers RAAT implementation generally. Roon just acts on what it gets back from any device.
Any update on this? @ROSEHAN @ROSELOA I am (or was) about to purchase a 130 and I want to make sure this will work with my Holo May DAC via I2S.
RS130 currently supports RoonReady.
Please look at the description below and compare it to your DAC to see if it is compatible.
Thanks for the reply @ROSEHAN. The image you sent says DVI to HDMI, but the 130 has HDMI out not DVI, so 19 pins vs. 24. The Holo May has 4 settings picture attached. Can you confirm, if one of these will work with the 130, and given the comments from others will it work for DSD?
It works, I use the RS130 with Holo May KTE

@Bitspeed Thanks for confirming. Can you comment on how youāve configured it and how it performs vs. the USB interface? Can you get DSD 512 with roon?
Currently my RS130 still downsamples from DSD256 to DSD64 over I2S while streaming Roon. Through USB thereās no downsampling, but I donāt own a high quality USB cable yet.
That sounds disappointing. A high quality cable should not be what determines the resolutionā¦ Some might argue they do nothing ā Iām still undecided but open to hearing a differenceā¦
Also discouraged to hear official responses from ROSE that call out the wrong connection DVI vs. HDMI. Did I make a mistake ordering this thing?? Time will tellā¦
