Hi Todd H,
Here are a few possibilities.
You mentioned that you tried a lower DAC link. Did you try them all?
This may be a needless question, but did you follow all the steps in the manual for setting up Bubble UPnP?
The error message you received for Bubble UPnP can be due to a momentary interruption in the WiFi / network service (which otherwise would seem to operating properly) or for some other reason an inability to access the music library. With respect to the latter possibility, that sort of network / access interruption might also occur along with the screen brightness change and that would negatively impact Bubble UPnP.
In the past another Forum member reported that If the Bubble screen on his remote device was not turned on, he could only get one auto advance to the next track and then music playback would stop after playing this second track. His solution was to click on the cover of the track that was playing to maximize it and this would keep the screen on. The tracks would auto advance and music playback would continue. So does your screen remain continuously on when using Bubble UPnP?
