WMA Lossless and SuperUniti

Posted by: Philippe Hebert on 04 September 2012

Hi,

I have a SuperUniti, and my entire music library is in WMA Lossless. I don't want to use another lossless format like flac as it is not recognized by some of my devices.

1/ Do you know of there is a chance that a new SuperUniti firmware will support WMA Lossless?

2/ When I pull the stream with the SuperUniti from my Windows Media Player UPnP Server, is automatically converted to LPCM and works perfectly. But when I push the stream from the Windows Media Player interface to the SuperUniti it doesn't get converted and I receive an error. Do you know how to fix it, as the Windows Media Player interface is much more user-friendly than the green Naim's screen?

Thanks for your answers!

After different researches, I have founded a solution that might be interesting for others.

There is a part of the SinkProtocolInfo of the SuperUniti which makes the "Play to" function of Windows Media Player not works when using WMA Lossless files.

Here is the solution:

You have to create 3 keys in the registry:

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows Media Player NSS\3.0\DeviceShims\Naim Audio Ltd.]

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows Media Player NSS\3.0\DeviceShims\Naim Audio Ltd.\SuperUniti]

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows Media Player NSS\3.0\DeviceShims\Naim Audio Ltd.\SuperUniti\20-004-0007]

Which correspond to the Manufacturer, Model Name, Model Number founded in

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows Media Player NSS\3.0\Devices\...

Then in [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows Media Player NSS\3.0\DeviceShims\Naim Audio Ltd.\SuperUniti\20-004-0007] , add this entry :

"SinkProtocolInfo"="http-get:*:audio/L16;rate=44100;channels=1LNA.ORG_PN=LPCM,http-get:*:audio/L16;rate=44100;channels=2LNA.ORG_PN=LPCM,http-get:*:audio/L16;rate=48000;channels=1LNA.ORG_PN=LPCM,http-get:*:audio/L16;rate=48000;channels=2LNA.ORG_PN=LPCM,http-get:*:audio/L16;rate=96000;channels=1LNA.ORG_PN=LPCM,http-get:*:audio/L16;rate=96000;channels=2LNA.ORG_PN=LPCM,http-get:*:audio/L16;rate=88200;channels=1LNA.ORG_PN=LPCM,http-get:*:audio/L16;rate=88200;channels=2LNA.ORG_PN=LPCM,http-get:*:audio/L24;rate=44100;channels=1LNA.ORG_PN=LPCM,http-get:*:audio/L24;rate=44100;channels=2LNA.ORG_PN=LPCM,http-get:*:audio/L24;rate=48000;channels=1LNA.ORG_PN=LPCM,http-get:*:audio/L24;rate=48000;channels=2LNA.ORG_PN=LPCM,http-get:*:audio/L24;rate=96000;channels=1LNA.ORG_PN=LPCM,http-get:*:audio/L24;rate=96000;channels=2LNA.ORG_PN=LPCM,http-get:*:audio/L24;rate=88200;channels=1LNA.ORG_PN=LPCM,http-get:*:audio/L24;rate=88200;channels=2LNA.ORG_PN=LPCM,http-get:*:audio/wav:*,http-get:*:audio/x-mpegurl:*,http-get:*:audio/x-ms-wmaLNA.ORG_PN=WMABASE,http-get:*:audio/x-ms-wmaLNA.ORG_PN=WMAFULL,http-get:*:application/ogg:*,http-get:*:audio/mp4:*,http-get:*:audio/x-flac:*,http-wavetunes:*:audio/x-ms-wma:*,http-get:*:audio/x-aiff:*,http-get:*:audio/x-m4a:*"

It works!

In fact this SinkProtocolInfo is the same as the original, but I removed: "http-get:*:audio/mpegLNA.ORG_PN=MP3,"

Now all my WMA Lossless files are transcoded in LPCM without quality impact, and I can use the "Play to" WMP function.

I didn't succeed to figure out if it is a bug on Naim side or on Microsoft side.
