Oh, that's different then: the problem is with the UPnP bridge, not
with
any other player?
Yes, that seems to be the case.
* With a Boom I can play 24 bit wav files perfectly, did not check if
conversion from wav to pcm is done.
* With Squeezelite 1.8 on a PI connect via USB I can play 24 bit files
also, but they are not bit perfect, which is because wav is converted to
pcm. The PI is connected to the DAC which is able to check if playback
is bit perfect or not.
* The renderer in the DAC, which is connected via the upnp bridge, is
not able to play the 24 bit wav files.
, at least I can hear nothing. The log showed that no conversion is done
and I am sure it worked before, because a few months ago I was able to
update my DAC’s firmware by playing a wav file exactly the same way I
try it now.
So defenetly something must have been changed, but I do not know where
to look for the problem and if it is because of changes in LMS, the upnp
bridge or even because of a setting in DAC :-(. I do no upsampling or
something like that and the settings for LMS and the DA
C did not change since the last working firmware update.
The renderer in the DAC is working out of the box with the upnp bridge,
there was no need to change anything in the upnp bridge settings to make
gabbles playback and other things working, which cause so ofthen
problems with other upnp devices.
And like said, it worked perfectly a few months ago...

WAV to PCM is not a conversion, this is bit perfect. Now of course the
header is removed, but that's not altering audio. Now, we'd need to know
what your DAC expects to do the update, but the header should never have
been sent to the DAC anyway, although there was some bugs here in the
past.
Sorry, I can not tell in detail how the DAC is handling the wav file I
need to play for the update, but maybe someone can find out more when
looking at the file or can tell me how to find out more about headers
and co:

Yes, things have changed to get fixed which, as I said, might come with
mistakes I've made. Let's see what your DAC expects and figure out while
it does not work anymore
@philippe_44, thanks again for your great work for the LMS community and
your support. Its no problem when there are errors and its not important
to me if playback is bit perfect or not when listening to music, I just
wondered why the last firmware update for the DAC worked and the current
update is not working any more.
I'll send a log file for the upnp bridge later this evening. Maybe there
are more details about whats happning when trying to play 24 bit files
via the renderer of the DAC.
Regarding the update I was able to perform it with another player I have
by using the app for the player (Lumin) and by connecting the player via
USB to the DAC. The firmware file has been offered by minidlna which is
also running on the same machine that runs LMS.
Lets first concentrate on the issue why I can not play 24 bit files via
my DAC's renderer anymore. If this is working again, we can try to find
out why the DAC is not recognizing the fimrware file as bit perfect.
Cheers,
Schoepp
