I wonder if I can be given any assistance into an issue I am
experiencing.

I use lms-to-upnp to bridge Roon with my Naim NDS.  It's been working
well for 2 years.

However have identified an issue with mixed format playlists.

If I have a playlist which has a 24/192 track and the next track is say
24/96 when the track finishes it does not advance on to the next track. 
I can go the other way so 24/96 to 24/192 is OK.

24/192 tracks seem to be the only issue.  i.e. if I have a 24/96 track I
can advance to a 16/44 track OK.

I can work around this in one of 2 ways.

1. If I set stream_length to -2 the track will advance.  However the
last 10 seconds of the track doesn't play, i.e. it advances 10 seconds
too early.  This happens for all tracks regardless of format so isn't
really workable.

2. If I set FLAC compression in Roon to on then I don't see this issue. 
I don't want to do this as Naim streamers perform best if they receive
PCM/WAV and don't have to transcode.  If I get lms-to-upnp to transcode
FLAC to PCM that track advance issue is reintroduced.

One thing I have noticed is that 24/192 files show as being played as
WAV if I check on the streamer whereas all other formats show as PCM.  I
wonder if it's the change from WAV to PCM that causes the issue?

I've tried many permutations of settings and cannot seem to get to the
bottom of this so any help would be appreciated

Here's the Common section of the config file

<common>
<roon_mode>1</roon_mode>
<send_metadata>1</send_metadata>
<auto_play>0</auto_play>
<seek_after_pause>0</seek_after_pause>

<volume_feedback>1</volume_feedback>
<resample_options></resample_options>
<flac_header>1</flac_header>
<accept_nexturi>1</accept_nexturi>
</common>

and here is the device specific section

<device>
<name>Sitting Room</name>
<mac>bb:bb:f6:b1:d4:f3</mac>
<friendly_name>Sitting Room</friendly_name>
<udn>uuid:5F9EC1B3-ED59-79BB-4530-0011F6B1D4F3</udn>
<enabled>1</enabled>
<accept_nexturi>1</accept_nexturi>
</device>


Thank you
