Hello @AlexJ,
Can you send me a copy of the “Debug Info”? You can get it in Audirvana Settings>General>Debug Info
Note: By clicking on the Debug Info button, Audirvana automatically copies all its content, all you have to do is paste it in response to this message
to edit your post you need to click on the three dot option next to Reply button 
Debug info below. I think this is not the info you are looking for, because I did shut down my PC yesterday, so I think all relevant information about yesterday’s night session is lost. Let me know if this is useful already, or you need more information (Then I will also power up the Pi4/Moode and listen some songs, after which I will share the debug info).
About editing posts, Im sorry to say, but when I hit the " …" I can ‘share’, ‘bookmark’ and ‘delete’ the post, not edit.

Hi im quite new here and um not sure if this is solved but ihad the same problem so i changed my output to WASAPI from ASIO and everything works perfectly
16 bit plays as 16 bit and 24 bit plays as 24 bit. same for tidal files
im not sure about how to fix this issue in mac though…
Hi all, I’m using Audirvana 3.5.42 with Windows 10 and Cambridge Audio USBAudio ASIO Driver on a CXA81 playing from Tidal source.
I’ve the same problem with bit depth but also with the sampling rate: 24/192 FLAC are played at 32/96.
Here my debug:

Is this an MQA file?
Yes it is an MQA file.
Then it’s normal since your DAC is not MQA capable you only get the first unfold.
Thank you Alex! I didn’t understood that MQA it was a specific codec and not an acronym identifying an authorised source and quality of music.
So the DAC upscale the bit depth and downscale the sampling rate?
In your opinion which are the downsides?
No, you only get the full rate if you have MQA capable DAC.
Yes, now it’s clear; but why Audirvana says me that the DAC is rendering at 32/96? I can understand the lower sample rate but why the bit depth is higher?
What’s happening?
32 is the max bit depth your DAC supports.
Hi… the bit depth shown in Audirvana (and Roon as well) is NOT the bitdepth of the MQA audio but the bit depth of the FLAC container itself that holds the MQA.
Apparently a huge amount of 16bit MQAs were in the past rolled out in 24bit containers. Especially during the release of the Warner 16b/44.1k albums lots of the 16b MQA’s came mistakenly in 24bit flacs. It took a while before someone noticed, but in the mean time the majority has already been rewrapped correctly in 16bit containers (flacs) and so they are now also correctly showing 16b when playing.
When you see 24b and you see a samplerate >48kHz you can be certain it IS a 24bit.
However when you see 24b and the sample rate is 44.1kHz then there are 2 possibilities :
Those can - until this is fully solved - be identified only by looking at the bitrate (which I think is not possible in Audirvana). A true 24bit MQA flac has most of the times a bitrate of around 1500kbps.
For a 16bit MQA the bitrate is usually around 900kbps.
So if you see 24b and the bitrate is only 900kbps… you can be quite certain it’s actually a 16b MQA playing !
(I noticed quite some of Aretha Franklin with a bitrate of 900kbps still marked as 24b)
Hope this helps.
MQA_Tester thanks for the explanation, you’ve added another interesting element!
Now we’ve made clearness around the MQA topic, but it remain open the fact that in the output device section Audirvana for every input song’s bit depth shows always 32 bit depth. 
This was addressed by @Antoine before. He claims that what’s shown there is the max input bit depth the interface presents to Audirvana and that no padding or resampling is going on.
Ok, so it’s a viewing “bug” let me say. Thanks!
