Hi there
I’m experiencing similar issues with the Argon Solo device.
I just got two of these a couple of weeks ago and they both showed the issues from the start.
Streaming from Tidal they are running relatively stable. However, I have had the disappearing you describe 5-10 times these past two weeks. They keep working as Chromecast and Airpaly devices. Only way to get them back in RAAT is to recycle the power.
I have also seen the “Starting audio playback on your device, this may take a moment” multiple times.
Another issue I have is streaming Live Radio via RAAT to the Argons. Playback just stops after 10 - 30 minutes. This happens every single time i try.
It could be interesting to see if you could reproduce this issue…
I also reached out to Argon support but they haven’t replied.
