This seems to be now correct and if it still does not work (i.e. no

No, your receiver does not advertise itself as being capable of receivng
24 bits PCM. It does not mean it cannot play 24 bits, but at least it
cannot receive that as pcm. Look at the lines
Code:
--------------------
http-get:*:audio/L16;channels=2;rate=96000:DLNA.ORG_PN=LPCM,
--------------------
Each of these line indicate a capability of the player. It means it can
receive, using HTTP protocol, and mime type is PCM format in 16 bits, at
96KHz and stereo. Any 24 bits line would be of format
http-get:*:audio/L24. NB: to indicate flac, the line is
http-get:*:audio/flac (mime type audio/flac)
Likely, JRiver simply truncates samples from 24 to 16. You can do that
as well in my bridge by choosing for 24 bits PCM: "16 bits raw only".
This means that when receiving raw pcm audio, truncate them to 16 bits
if player does not support 24 bits. But when receive wav files, do not
apply truncation as some players accept 24 bits in wav files (I suspect
they truncate them, but that's another discussion)

ReplayGain must be applied by the player itself, not by LMS. So yes, LMS
does the transcoding to flac, but does not applies ReplayGain. My
bridge, which acts as aa "virtual player", seen from LMS, receives flac
and simply forwards it to the real player, so i does not see eithe the
raw samples, hence ReplayGain cannot be applied. I would need to decode
the audio. I have support for that now, but I don't intend to activate
it.
