LMS when output pcm ALWAYS reports to clients the samplerate of the
original file. BUG or feature by design I don't know, but it's like
that.
To solve this, leaving LMS untouched, I've introduced a patch in
Squeezelite (R2) that use data in the header to detect the actual sample
rate. You could use option -W in squeezelite by Ralphy, squeezelite-R2
(https://github.com/marcoc1712/squeezelite-R2/releases) or Daphile.
All of them includes R2 patch. Please note that you then have to produce
WAV or AIFF, not raw pcm to let things works this way (just replace raw
with wav in sox command).
C-3PO plugin (https://github.com/marcoc1712/C-3PO) is a replacement for
custom-convert.conf files and File Types, aimed to make things easier.
I'm gonig to release a new version of Squeezelite-R2 and C-3PO capable
of PCM to DSD transcoding and 'native' DSD playback (thanks to Daphile
and Mans Rullgard).
