I have checked that all cue files in my music library do not contain
REPLAYGAIN directive.
All cue and flac files are ripped by Exact Audio Copy from CD.
They are all 16bits/44.1khz music files.
Thanks for all. :)

Me neither. Whenever I encounter any such file I use it to split the
wav/flac/ape and (re)code the individual tracks to CD quality flac (16
bit). Which I'm pretty sure that the software also does when the input
is flac already, so it's not a simple `dd`
I don't use CUE file or know CUE files very well but there was a recent
problem about an EAC generated unsupported variant of CUE file. I
vaguely remember there were "REM REPLAYGAIN_TRACK..." and "REM
REPLAYGAIN_ALBUM..." directives - not sure if LMS processes them.
It seems to me to be sensibl

That, and also what hardware you run LMS on and what other duties that
machine may perform in you
indeed theres a trade off in many respects, at the time i felt that
taking the load of the touch cpu and getting the server to decode from
flac to pcm was an improvement. I've not bothered since I moved to
Picoreplayer throughout.
when i finish rejigging my main system I might have another play
A long time ago this same argument played out.
SQ isn an individual opinion but if belief is based on lower CPU load so
lower noise etc. - it has been measured that a PCM stream has a higher
CPU and I/O load on Touch than Flac due to higher network and larger
amount of data been transferred betw
default is send flac,
from memory you can turn off flac native in the server settings and make
sure transcode to PCM is the only one left ticked.
however that affects all players
If all your players support PCM directly thats fine, if not you are
messing with one of the config files directly
