I had a similar issue (or non-issue) in the past with my Sonore renderers.They showed as bridges, and I thought they lacked advanced settings. This was until I realized I did not scroll past the “Show advanced” mark. The infos past “Show advanced” are not displayed automatically, you have to force scrolling to see them.
The fact that Sonore streamers show as bridges and not as audio devices is normal. They are not audio devices, they connect to audio devices. In your case the audio device is an Hegel H390.
Could you check all that in your setup and report ?
