MQA playback with a PS Audio PerfectWave DirectStream DAC / Roon Nucleus

Roon Core Machine

The Roon Nucleus is:
serial #54b2038b16e
version 1.0
build 254

Networking Gear & Setup Details

I use a chrome book as a remote I should be on the latest roon update but was unable to locate any info. chrome version 111.0.5563.71

Internet enters via a comcast modem. It is cat 5 to a synology rt2000ac. that is cat 5 to nucleus and to a dlink 1005g switch which is cat 5 to bridge, this is the same setup when mqa worked, nothing has changed in the hardware.

the dac drives a parsound jc2 pre amp and jc1 monoblocks.

the roon also drives 5 sonos legacy (1st gen) endpoints.

I do have a synology NAS but it is not connected to the system at this point as I only stream Tidal at this time. There are about a dozen albums on the nucleus’s internal 1 gig drive.

Description of Issue

Playback for MQA files seem to work fine, however the MQA notification / light is NOT working. I have confirmed that this feature works on the PS Audio DSD using a different setup (connected directly to a PC with Roon over USB).

Is Roon doing the first unfold?

Can you past a screenshot of Roon Signal path when you are playing a MQA file.

I’ll work on getting a screenshot. The DirectStream DAC is set to handle MQA decoding & rendering
