I looked a bit more and had to refresh my memory. The issue seems to me that when we use "I" and seek, then LMS does a HTTP range request to reach the guessed offset (I worked on that flac header parsing & building for 8.0) so the flac decoder does not have a STREAMINFO header, it's just streamed flac. In that case, it does not seem to rebuild a proper WAV header and as consequence sox fails to resample. This is what I observe in the conversion log. I feel it can be fixable by either forcing flac decoding to build a proper header or by using raw and giving sox the raw parameters LMS 7.9 on Pi 3B+ & Odroid-C2 - *SqueezeAMP!*, 5xRadio, 3xBoom, 4xDuet, 1xTouch, 1 SB3.
