So, I recently picked up a Musiland Monitor 02 US DAC. I posted in the Dedicated Source Components thread, but that doesn't seem to be the correct place where people are asking for help.
I read through the entire Musiland Monitor 02 US thread, but no one seems to have the problem I am, which leads me to start a new thread.
 
Currently my soundcard is an Audigy2 ZS. Hooked up via coax, outputting at 24/96 to my Maverick Audio D1. Works great. The D1 accepts 24/96 max over optical/coax.
 
I'll TRY and make this the simplest I can. Simply put:
The Musiland can be used as a transport. USB -> SPDIF converter. Optical/Coax out, as well as analog outs.
Connecting the Musiland to the D1 via SPDIF is the problem. (Optical seems not working so this will all be about coax.)
 
Through foobar, the WASAPI/ASIO feature allows bit perfect to be sent to the audio device selected. Sending 24/96 through my Audigy2, audio works. However, sending bit perfect 24/96 media through the Musiland, no audio.

 

The Musiland has an option to set the sample rate to a fixed rate, so I set the fixed rate to 96, playing anything such as MP3's via WMP, no audio.

Setting the sample rate to 44/48, then playing 24/96 media through WASAPI, the Musiland automatically changes the sample rate to 96, and audio doesn't work.

Once I set the sample rate to 44/48 on the Musiland, I hear the D1 making a "click", and audio works with any regular audio from the computer. (The click is the D1 detecting the signal internally.)

 

Of course, over the analog out on whatever sample rate from the Musiland to the D1, it works.

 

--------

 

I've tested this with the AUNE amp/dac, as well as my Logitech Z680. Both over coax.

The AUNE and the Logitech Z680 both accepts 24/96, and audio works with both.

So I can conclude that there's nothing wrong with the Musiland. It's not the drivers. I've tested multiple drivers, and the AUNE and Z680 still works.

 

It's JUST with the D1. The D1 accepts 24/96. If it's accepting 24/96 through my Audigy2, why won't it work with the Musiland? 

Does ANYONE have any idea?

 

Here's a picture of my settings. I believe I'm doing everything right, as it's the same with my Audigy2, except the device is the Musiland now. I've tried almost every setting, every combination. Nothing works. There seems to be a problem with the Musiland and the D1 ONLY @ 24/96.

Don't mind that there's nothing active in the volume bars. As you should know WASAPI bypasses WDM and goes straight to the audio device. It's the same thing when the sample rate is 44/48, which works to the D1.

[size=10pt]Don’t think this has anything to do with the drivers used (WASAPI, ASIO, etc)[/size]
[size=10pt]In case of SPDIF a stream of bits is send to the receiver.[/size]
[size=10pt]The receiver read the bits and generates the sample rate from the speed of the bit stream.[/size]
[size=10pt]It look like that the D1 has problems locking on the bit stream of the Musiland at higher sample rates.[/size]
[size=10pt]This might because the D1 is very sensitive to input jitter or the Musiland generates a higher than average amount of jitter.[/size]
[size=10pt]As other combinations seems to work, I do think this the most likely explanation.  [/size]

Roseval, thanks for the reply. 
 
Your explanation seems to be the most logical and possibly only explanation too if you think about it.
 
Would anyone know anything about the jitter?
Man! Such a waste! Getting a decent usb transport for the D1 and it doesn't work haha.
