We are enjoying our music with MinimServer 2(full license) + MinimWatch 2...

It goes well with DSD 2.8MHz and DSD 5.6MHz,
but can't play DSD 11.2MHz native...
the streamer set up like this:

stream.transcode = dff:dopwav, dsf:dopwav, flac:wav24

Thanks ahead for any help!
Are you sure your player is able to play DSD 11.2? What device are you using to run MinimServer?
We run Minimserver on Qnap T328, and the player is Linn Kazoo.
Our DAC is Matrix. We can play DSD 11.2 with Matrix's own player.
This is our local music network set up:
DAC and NAS connect to router with lan cables, Linn Kazoo on tablet connects to router with wifi...

Thank you!
Which model of Matrix DAC do you have?
It's Matrix element i

The specifications for this model (this page) say under USB Audio that the device can play up to 5.6 MHz DoP and up to 11.2 MHz Native. Because you have set stream.transcode to use DoP, you are limited to 5.6 MHz.
Hello again ,
we are not using the USB input into Matrix , hardwired Ethernet cable LAN to the QNAP and Router ...all working fine and we did some upgrading and testing this weekend ...we have now no trouble streaming from Qnap via Qfile direct to the Matrix at 5.6MHZ /11.2 MHZ native , it works , bit we still cannot do this via the Kazoo Linn actually gets the Hi/Res files , plays , but there is no sound ...!!!! Put the ear to the speaker and there is a very faint , in summary we think it is a Kazoo app limitation ...!!!
would be nice to be able to get a way around that , can the transcode limit be increased on your steamer ....??? as the Matrix app is crap , or alternative get around using another app ( Lumin ) if there is a way without using a Lumin DAC or Streamer ....much prefer your system...

And the last, can we set stream.transcode to use other code except Dop???
Thanking you for your help...!!!
If the Matrix cannot support 11.2 MHz DoP over USB, it is almost certain that it cannot support it over the network. Your experience confirms this.

Kazoo is not involved when a file is playing, so the issue is not related to Kazoo. The DoP audio stream goes directly from MinimServer to the Matrix.

When you use QFile to stream to the Matrix at 11.2 MHz, is this using native or DoP? If it is using native, it seems clear that the limitation is with DoP support in the Matrix.

To stream 11.2 Mhz DSD from MinimServer as a native stream, you need to remove the dff:dopwav, dsf:dopwav setting from stream.transcode and restart MinimServer. If this doesn't work, you might need to use the mimeType.dsf and mimeType.dff options in the serverOptions property to set custom MIME types for DSF and DFF files. See the Custom MIME types section for more information. Matrix Audio should be able to tell you what values to use for these custom MIME types.
We never play Dop over USB on Matrix, actually until we use minimstreamer setting up Dop to play DSD that we first time knew about Dop...

And we are not sure how the Qfile stream the DSD 11.2MHz native to matrix, we only updated its firmware, then it can stream all kinds of DSD to matrix and play well.

every time we play DSD,no matter which player we use(matrix app, Qfile or Kazoo), the matrix will show the exact file information on the screen, such as DSD2.8m,DSD5.6m or DSD11.2m native.
We found another thing is that when we play DSD11.2m native with matrix app or Qfile streaming, if we open the Kazoo, we can see it also plays the same music, but the information shows 1.4MHz...don't know if it has something to do with Kazoo or minimserver?

And thanks for your advice, we tried our best as below,

->remove the dff:dopwav, dsf:dopwav setting from stream.transcode and restart doesn't work, we can not play any DSD art all...

->set up custom mimeType. To be frank, it's very hard for us to understand what it is and how to set up this. We are a couple who live in the bush f down under in Australia. The husband is nearly on his 80s, learning DSD DOP DFF NATIVE DSD etc / via Google is not all that easy...English is our second language , we are trying. Still no idea what MIME is...and Matrix would be a waste of time asking , sooo...
so, we only tried to fill in the server options property as below:
it didn't work. even with a higher x10 number , no DSD at all..

with Qfile, over DLNA , we can stream all DSD files , including Native DSD 11.2 Mhz , direct to Matrix , that's with Minmin Streamer shut down...
with the Minim on and the dff:dopwav,dsf:dopwav back in it's place , we can listen to DSD 64 and DSD128 , but not DSD256/11.2 Native DSD...
to us , that means the Minim Streamer is restricting the flow and helpfully you can send us the correct code....

Thanking you from down under ....!!!!
I will do my best to help you to get this to work. I could give you a technical explanation of the 1.4 MHz but this wouldn't help solve the problem. It is related to using DoP to stream the audio.

Your setting of mimeType.dsf=audio/4x-dsd,mimeType.dff=audio/4x-dsd is not correct and changing the 4x to a different number will not help. Instead, try all the following until one of them works (hopefully):


You need to restart MinimServer each time you change this and it would be a good idea to restart Kazoo as well.

I have tried to use QFile to see what format it is sending but QFile is unable to find my music player on the network.
