Description Of Issue
I’m using a Roon Nucleus+ to send data via USB to my DS Sr. I have told Roon to send DoP with max sample rate DSD set as up to 128. I have some 128 files that look like they are playing, but I get no audio until I engage DSP Sample Rate conversion. Sample rate conversion only works if I set it to convert DSD 128 to 352.8 kHz. No audio with conversion set to DSD 128, or to DSD64. I tried clicking the use defaults button in Roon device setup which did not resolve the issue.

It seems to work as it should with the Bridge II engaged. I have setups for both as I use the bridge for headphone applications, and USB for speakers.

I don’t know if it’s me, Roon, the nucleus +, or the DS. I will post this on the PS audio forum also.

Has anyone else been affected by this?

Have you tried using the Directstream Bridge II’s Roon Ready ability and plug it into the switch, instead of via USB?

Hi @huang,

Is your PSAudio on the latest firmware? Testing it via Roon Ready as @Greg mentioned is also a good troubleshooting step.

PS Audio is not at the latest FW it is at Redcloud not Windom. Bridge operation is fine. I have two separate inputs going into the DAC. One ethernet, and one USB.

Hello @huang,

Later releases of Snowmass have updates to the USB chipset for better Linux compatibility. I recommend updating to the latest firmware to see if that resolves the issue you’re seeing.

Thanks John, just went to Windom. I will report back. There is not an issue with drivers, or anything on the Roon end correct?

It was successful. I am listening to Dizzie Gillespie - Stuttgart/Frankfurt '61, in 128 DSD with that lovely lossless light glowing. Thanks to all who offered suggestions. Being stuck at home I have been buying way too much music! If you buy it you gotta listen to it right?
