Anyone Any succes with USB-speakers on Ropiee?


I’m trying to connect a Bose Companion 50 USB speakersystem to a Raspberry Pi 4 with Riopee.
When playing music on it, I only hear a high frequency beep, and in the background a little bit of the music.
Anybody any experience with connecting USB-speakers (so with internal DAC) directly to the pi, in stead of a USB-DAC, and then speakers? Doesn’t Ropieee needs some drivers then?
I have Ropieee on another RasPi 4 with an Dragonfly Red and that works like a charm.

Thanks in advance!!
