Problems playing WAV files to Naim Unitiqute using Kinsky
Posted by: The Pied Piper on 10 January 2013
Dear All,
This follows on from a similar issue identified in 2010 when trying to play m4a files on a Naim Unitiqute with Kinsky.

(followed up by Steve H from Naim R&D).
WAV files will not play using the latest version of Kinsky on the Unitiqute and the problem was identified by Simon from Minimserver from the debug console report (at end of this message):
------------------------
Kinsky reads this list and sees that audio/x-wav (the correct MIME type
for WAV files) isn't on the list, so it won't send WAV files to the
Unitiqute.
Note that audio/wav is present in the list instead of audio/x-wav.
This is a Naim bug, as any MIME types that aren't in the official
IANA list are required to use the "x-" prefix. The official list is
at http://www.iana.org/assignments/media-types and you'll see that
audio/wav isn't included and that the 'x-' prefix should in fact be used.
-------------------------------------
I guess that audio/wav is used for backward compatibility and that n-Stream (which does not have the problem) uses audio/wav.
Could audio/x-wav also be aliased to audio/wav in the next firmware (as x-m4a was added previously)? This would then comply with IANA and allow other control points to interface with teh Naim Unitiqute.
-----------------------
I have tried Twonky with Kinsky and there is the same problem (with same debug console report).
