I've been running IdPi for a couple of months with no issues. The last couple of days about halfway to 2/3 of the way through playback all of my FLAC files are skipping to the next track when playing back from another device (Media Center 28 on Windows, Panel inside network, Panel outside network, mobile). The tracks DO NOT do this when I am listening via headphones connected directly to the Pi. MP3 files are fine in all scenarios. Tracks are on a repurposed SSD drive in an external case that is connected via USB to the Pi.
I've tried tweaking buffering, conversion settings etc. based on some other posts. No luck. Any thoughts would be helpful.
