Description Of Issue
Since about a week the music doesn’t sound pure anymore. It’s hard to describe: the song seems normal but at times it sounds distorted; like damaged compact discs sounded in the old days.
When I play the same song (regardless of Qobuz or private storage) through the Blusound app, it sounds fine on all devices.
For example: Mare Nostrum at 1:29 - see attachment.

Maybe something to do with the recent update for uncertified devices?

What is the signal path looking like…and dsp in play?

An update: since Sunday everything is working fine again. Just like that. Thankfully!
The question remains: what was going on last week when the playback quality in Roon was so poor, while there was nothing going on when playing from the Bluesound app?
