You seem to be having the same issue as me. I have narrowed it down a bit, it cuts out exactly at 29 seconds for me on any SONOS device that is S2, but an older model. My SONOS devices that are S2 but a newer hardware revision do not have this issue.
From what I found, I can play up to 24bit48khz (native SONOS support) through Tidal, Plex and directly through the SONOS library.
For those saying it is SONOS signal, I have gone through the support matrix and all devices are green. It also happens to the older S2 models that are hardwired. This only started happening after the latest SONOS firmware update to version 16.
