Where do I go In roon to change the dsp? It’s been down grading 48hz to 44hz

See this Help Centre article.

How are you playing Roon, via Raat, airplay, etc. And what are you playing it to?

Hi, thanks for responding.
Roon is using airplay to a anthem mrx 540, usually happens with tidal MQA.

Airplay only supports 44.1 for audio streams so it will automatically resample you can’t stop that or it wouldn’t play.
