Long shot, I know.
Are there any users on here that may have attempted/failed to install Studio on one of these streamers?
I ask because (and my memory may be playing tricks on me) I seem to recall, when I purchased this streamer, that the blurb stated that you could install different Linux builds on it as opposed to the tweaked Volumio that comes pre-installed.
I can’t locate a Pro-Ject forum to ask this question, however the Volumio forum would appear to suggest that installation of any software other than Volumio is doomed to failure, especially the wi-fi/network connections.
