I have a Rockna Wavedream DAC.I have connected Roon Nucleus+ to this DAC by HDMI cable.Rockna is not Roon Test，so this device can not be found in the list of the co-producers.Next what should I do？
I don’t know this DAC, but does a Nucleus support HDMI output? Can you try a USB connection instead?
I have also moved this thread to Nucleus Support, so that Roon’s support team can find it.
When you go to
Settings > Audio do you see options for HDMI output on the Nucleus?
HDMI of this DAC is i2s.I just use HDMI cable.I want to know that whether the Roon Nucleus+ support i2s connecting by HDMI cable？
Does the Roon Nucleus+ not use i2s protocol at HDMI port？I want to use i2s connecting.This DAC is available.
Does that mean Roon Nucleus+ do not support i2s protocol？
it uses HDMI for video so no it doesn’t support i2s on it. Like any normal computers HDMI port would - to a monitor. Hope you havent damaged the interface of either as they are not electrically compatible.
No, not electrically compatible. Disconnect them immediately before you do any further reply.
Before you purchase a DDC, check the pin compatibility, especially if the DDC I2S pinout is not or only have limited configuration options.
If you don’t use a DDC or a streamer, connect it via USB.
Roon Nucleus+ USB connection Rockna DAC sound normal.
