Problem playing DoP from SB Touch via SPDIF to Devialet

As captioned, tried playing DoP via Roon to SB Touch to my Devialet, connection is via SPDIF.

The music did come out but with a layer of static masking the music.

Is this a common problem with SPDIF?

I seem to recall USB was working fine playing DoP natively when I tried last time. I did not have time to try USB again. May try tonight if I have a chance.
