Have you connected the DAC directly to the computer using USB?
Just did that. Then it wonāt play as 16/44 but 32/44ā¦
Whatās the reason for askingā¦? I tried it to hear if it has anything to do with ethernet or somethingā¦because the humm sounds like a electrical distortion. An other ethernetcable didnāt helpā¦(and the microrendu has the same humm/buzz as the stack audio ). I canāt be the streamer/bridge.
The only thing, besides the audirvana software, that can cause the problem is the Qutestā¦ But why only at 16/44?
And why did it start with audirvana and Roon was hummless/buzzlessā¦ So theoretical it canāt be the dacā¦
Iām gonna try another powersuply for the quetestā¦just to make sure.
Nothingā¦same same. Iām out of optionsā¦
Playing 24/44,1 files bitperfect; no problem no buzz
Maybe somethingās up with the file youāre testing with. Try with some other file.
Just have the DAC connected directly to the PC, disconnect everything else.
ā¦it happens with all my nas files, qobuz files and tidal files(before)ā¦
I just connected the laptop to the qutest again and it wonāt play 16/44, but 32/44.

Thatās normal. The bit-depth you see on the right side is allegedly what is reported by the USB interface. How does it sound? Is the hum gone?
ā¦the humm is gone. Left it says 16/44, right it says 32/44.1 (pc to dac)
(Pc to bridge to dac) ; left 16/44 1 and right 16/44.1
So,the hum is gone when i DONāT use a bridge/audirvana endpointā¦ such as Stack audio link 2 ā¦or microrenduā¦
Whatās the overall conclusion?
Use USB? 
Thereās something with Qutest when interacting with Linux in the bridges, or it may well be UPnP related issue. It would be interesting to try with RPi based bridge and RoPieee XL, for example.
Use pc with usb you mean?ā¦
No optionā¦ thatās were i bin and thats why i bought a microrendu and last month the stack audioā¦and audirvana .
But still, to me, it is not making sense because its only at 16/44ā¦ If there IS a oroblem with the qutest, it would act the same at al bit depthsā¦ ?
Conclusion and choices;
-Only use forced upsampling
- buy another dac
- use another software programm (but i just bought a license)
Am i the only Qutest user with this problem?
Rather than changing the DAC, which is decent, I would think about getting another bridge.
Have a look at Allo USBridge Signature:
or DigiOne Player:
With that one you could use it with BNC SPDIF connector. If you donāt care about DSD is probably the best option.
i am really thankfull for your help and energy that you put in this problemšš»ā¦ But my mind canāt believe that a microrendu or a stack audio link is the problem. They both advertise as a audirvana endpoint.
I also canāt believe it is the quetest and why only at 16/44.
With Roon and volumio t6hw qutest worked fine with the microrendu.
it all started with audirvana and the microrendu and now with the new stack link 2 it continuedā¦but only at 16/44ā¦
my first post was about my disappointment of buying a audirvana license and having a hummā¦
In the audirvana trial there was no problem. Then i switched to Roonā¦and back ro audirvana because of the soundā¦i bought a license, installed itā¦and the humming beganā¦ With the microrenduā¦
I was told to upsample so the humming would be gone.
As i upsample there was sometimes a big loud noise and iām surprised that it didnāt ruin my tube amps and speakersā¦ terrible noise! From out of nothing.
So i bought some extra ram memory for my laptop to stop thatā¦ It didnāt stop. Even if i deactivate upsampling.
Then bought the stack audioā¦ nothing changed
So then i wanted to play bit perfect, but there was that humm againā¦ And now the advise is to buy another bridgeā¦
What can I say, itās a journey. Do you have another DAC you can try with microRendu and the other bridge.
Roon uses another protocol, so it may well be related to UPnP, therefore it would be interesting to check with another DAC and the microRendu. That would confirm if the issue is related to UPnP or not.
Okayā¦roon is different protocol. Maybe i try volumio and see if it brings the same problemā¦ another dac, wellā¦i can try to arrange one of my son.
And i know; its a journeyā¦ a really nice journeyā¦some things are not logical and then you search and findā¦ So iām searchingā¦
Hi, thank youā¦yes,i bought the newest version 3 months ago. But at the moment iām not using the microrendu ā¦the microrendu that was humming at16/44ā¦ and went with the stack audio link 2ā¦ And the humming stayed.
But as mr Razor says; probably a upnp thingā¦ donāt knowā¦
At this moment when i activate upsampling there is clicking sounds, and after 4 seconds the volume goes really loudā¦and then the distortion comes inā¦ Terrifiedā¦believe meā¦
So later on iām going do disconnect en connect the qutest again and the stack audioā¦and hopes this distortion stopā¦ Iāl try volumio and see what happens en try to get another dacā¦

ā¦ thinking again; the quetest needs a windows driver to work correctly.
I installed that driver.
I can now click on that driver in audirvana and play music from my laptop, usb, qutestā¦and itās all good.
But if i want to use my microrendu or my stack audio link 2, i have to select that option in audirvana so i can play music from laptop, microrendu or stack audio link 2, usb, qutestā¦ And thats where the hum appears.
My question; the windows driver that i have installed is it also working when i select microrendu or stack audio link 2? Is the driver inplemented in that option/selection?
Or with that option you donāt need a driver?
This evening i choose not to test with another dac because i want The Qutest as a dac. And i donāt want another endpoint, or volumio software ā¦so im gonna try to solve the problem eith audirvana bit perfect or go back to roonā¦ But to be honoust iām not a roon fanā¦
Another question;
Why is the bithdept 32/44 when playing laptop, usb, Qutestā¦and that same song 16/44 when playing laptop, stack audio link 2, usb, Qutest?
Without upsampling.
And is there an option to play everything bitperfect no upsampling except the 16/44 files so i can upsample them to 24/44 so there is no buzz?
