Having recently started to digitise some of my vinyl collection to 24/192 FLAC files, I've noticed periodic warbling distortion on playing the files, always part way into a track, never at the beginning. If I go back and replay the tracks they play perfectly. I did convert a couple of LPs when I originally started experimenting with the Pi/Rune system and didn't notice such distortion then.
CD's converted to 16/44 files play perfectly.
The files are coming off a NAS drive via a hard wired ethernet connection, although this is via a TP-Link AV500 powerline adapter. I guess this could be the cause of the problem. I've tried increasing the audio buffer size from 2048 to 3072 with no improvement.
Is there anything else I can try to solve this problem?
Using a Pi 2, with IQAudioDac.
