LMS is no longer transcoding wav to flac with 0 compression when streaming to Squeezelite. Seems to sound better with a more organic feel to it.
Seems logical, since everything resides on the same single machine, transcoding to flac (with checksum) doesn't really have any extra benefits since it's not really "going the distance".
For the future ISO release I'd be implementing this as the default setup now (except for DSD which can do both).
