I've made the following confg changes:
Upon boot up, content loads and plays fine. Once playback is stopped and I attempt to play additional content it will seek sources, attempt to play the file (same result for remote vs. local content) this fails after a ~1sec attempt. Reloading the skin does not fix it, but rebooting the Pi4 does. If the logs above are insufficient let me know I'm happy to pull whatever else is needed.
