So, here is my take of the story, now that I have the file: The file is incorrectly encoded toward the end (verified with ffmpeg). Slimproto returns a decoding error when it reaches that part (verified with my SqueezeESP32). Remember that the decode error can happen long *before* the audio reaches the DAC, in fact it entirely depends how big is the output buffer. I think the error happens at the very last bytes of the file. When transcoding happens, the decoding error is not anymore raised by the player, but in faad and I think faad simply ends the decoding and passes everything it can to flac, to re-encode. So, the track is played till the quasi-end, hence it "seems" to work. When no transcoding happens (for example players all support mp4/aac), then all players will send a decoding error but some might send it sooner, some later, depending on their buffer's length. When LMS receives the decoding error, it stops playback, even if there is data in the DAC (output) buffer. I would suspect that your pCP have different buffers and/or different timing for raising the error, hence the Library pCP, when going directly mp4/aac *and* with another player will cause the "early decoding error" issue. I would have to look at LMS code, but I suspect things are different when a player is standalone. LMS 8.2 on Odroid-C4 - *SqueezeAMP!*, 5xRadio, 5xBoom, 2xDuet, 1xTouch, 1xSB3.
