I’ve been looking at the docs but I couldn’t find any useful instructions on how the make the queue continue playing after the first song. I did find on this page Technical Information - Music Assistant descriptions of:
- BASIC/FALLBACK
- NATIVE ENQUEUE SUPPORT
- FLOW MODE
but I was unable to find any options in MA that have these options and the instructions don’t have any pointers on where to configure this. 
I didn’t want to open an issue because I barely installed it and ran into this issue that seems to be my own fault, I’ve got to be missing something because this can’t be how MA is supposed to work.
I was using the Home Assistant Media Player for one of my Sonos speakers because I wasn’t able to get the SONOS plug in inside MA to recognize my speakers. I opened a separate thread on the community to troubleshoot that but I don’t have high hopes because I’m sure there aren’t too many folks with VLANs, SONOS, and MA
