All I can see from your log playing outside the library is that it is
trying to play wav (from pcm):
Code:
--------------------
codec:p, ch:2, s:24, r:44100
and:
<res
protocolInfo="http-get:*:audio/wav:DLNA.ORG_OP=01;DLNA.ORG_FLAGS=21700000000000000000000000000000">http://192.168.0.220:49157/LMS2UPNP/00-0d-4b-04-69-fe-idx-1.wav</res>
--------------------
So LMS looks as if it is saying it's 44100, and because the plugin is
assisting by cutting 24 bit back to 16 bit, sq2u and LMS agree no
transcoding is required.
However, that doesn't explain why the Pi DACs work, unless LMS is
transcoding 192000 to 44100 for some reason. I'm a bit unconvinced by
this. Could sq2u be assuming that 16 bit can't be 192000, and reporting
accordingly.
What does the log for the PIs say when playing a 24/192 track from
outside the library?
LMS 7.9 on VortexBox Midi, Xubuntu 14.04, FLACs 16->24 bit,
44.1->192kbps. LMS plugin UPnP/DLNA Bridge to MF M1 CLiC (to MF amp &
ESLs) & Marantz CR603 UPnP renderers. Minimserver (server) & upplay
(control point) to same & to upmpdcli/mpd PC renderers. Squeezelite to
Meridian USB Explorer DAC to speakers/phones. Wireless Xubuntu 15.04
laptop with firefox/upplay or Android 'phone with
Squeeze-Commander/BubbleUPnP controls LMS/Minimserver. Have a Touch
with EDO, plus spare, but unused.
