Could you post a screenshot of your signal path while playing a DSD file? The signal path is shown when you click on that (blue) dot in the play bar. Also Screenshots from the Audio configuration menu might help.
Well I really don’t know your setup but doesn’t the DSD to PCM conversion spit it out PCM?

I realize you are trying to assist @rm863, which is commendable, but DSD files on a Mac appear as “.DSF” or “.DFF” and not as “.M4A.” And there is no such thing as a “DOP .m4a album.”
It is increasingly apparent that your purportedly fact-based posts are often wrong. In addition to the above, see, for example, your demonstrably incorrect statements that: [1] Underwood HiFi is not listed on the Wireworld website as an authorized dealer; [2] USB cannot transmit native DSD; and [3] the Matrix cannot accept native DSD.
For the sake of the forum in general and this thread in particular, please try to resist the temptation to post a guess, idea or theory as if it were a fact.
Now back to trying to solve @rm863’s issue with the unwanted conversion of DSD to PCM…

Volume Control set to “DSP Volume” is the problem. Set it to “Fixed Volume” or “Device Volume”.

First of all, you’re rude and incorrect.
If you take any album stored in the .dsf file format (DSD Storage Facility) and use a program called ‘DSD Master’ and convert it to a ‘Hybrid DSD File’ or DOP file - it will convert it to a .m4a file extension(which is an apple lossless storage container). This means the entire album would be in…hmm, what?..(whisper)…the entire DOP album would be in a .m4a container…try it for yourself.
I was trying to better understand what file format/type he was sending the Matrix since he said he was sending DSD to his DSD Sr over USB using a MAC, previously without the matrix. There are several ways to do this…but the only way I know to do this is to send DSD using DOP(DSD over PCM).
To say that there is no such thing as a DOP. m4a albums is like saying there are no humans that will ever have worn red pants in the world cause I’m currently not wearing red pants - it’s idiotic - and an embarrassing comment to make for yourself.
What are the sizes of your DOP - DSD64 albums?..cause 1.5-2gb is roughly the size of my files. Again I was simply trying to rule out that he was not mistakingly sending ripped 16/44.1 PCM files.
Further, I did not say that Underwood HIFI was for sure not listed I simply said I could not find them among the listed authorized dealer listing. If you go back and read that post - I asked several times if people knew for sure that Underwood HIFI was listed since I couldn’t find it.
I can tell you are simply trying to push peoples buttons in lieu of helping since your post provided none of the latter.
Please submit your “help”, I want to see the master at work.
Yes, @mr-ryan-eickmeyer has been posting all manner of misleading or incorrect information. Yet you are “rude and incorrect”…oh well.

What exactly, that I said, was incorrect?
DSD Master hybrid files combine PCM (as ALAC) and DSD data into a single file. You need to be running Bit Perfect, as you said you do, to extract the DSD component (Bit Perfect needs to be told the DAC supports DSD), otherwise the files will play as ALAC PCM. I imagine Roon would just see them as PCM. See http://dsdmaster.blogspot.com/p/bitperfect-introduces-hybrid-dsd-file.html
Bootzilla quite clearly pointed out three examples.
He isn’t trying to be rude, he is trying to help others.

As your statements are so often an inverse barometer of what is correct, I take this as a compliment.
Sorry, but it is not a “DOP album.” Rather, DoP is a background process invented by dCS that takes a native DSD data stream and packs it into a 24/176.4 PCM data stream. See: https://www.dcsltd.co.uk/support/what-is-dop-dsd-over-pcm/.
There is no need for the user to perform a manual file format conversion to utilize DoP. In other words, one simply plays the native DSD file, e.g., a .DSF file, and the DoP process works in the background to convert the .DSF file’s DSD data stream so that it can be read by a DSD DAC that accepts DoP.
I never heard of “DSD Master,” but I looked it up after reading your post. AFAICT from this description, “DSD Master” does not convert a DSD file into a “DOP file” (the terms, “DoP” and “DSD over PCM” are nowhere to be found in the DSD Master program link). Again, DoP is not a file format. Rather, it is a data stream conversion process that takes place in the background.
You appear to be laboring under the misimpression that DSD Master makes “DOP .m4a” files. According to the above link, however, what that program creates is “Hybrid-DSD” files (or “.DSDh” files). While creating such files is (apparently) a way of sending DSD in a PCM container, this is not the same thing as DoP. So I stand by my original statement that there is no such thing as a “DOP .m4a album.” Yes, I am doubling down on that statement, and I am not embarrassed to do so.
I have spent a lot of time on this thread and in PM’s offering to help with various Matrix-related issues. You may recall that you PM’ed me recently with a Matrix PSU issue. Here is the thread for anyone who is interested:
https://forum.psaudio.com/t/do-you-use-the-ifi-5v-power-supply-with-your-matrix/15565
Your final post in our PM thread stated: “Thanks for all your help!”
In the case of my most recent post in this public Matrix thread, I was attempting to help by pointing out factual errors in recent posts of yours. Don’t shoot the messenger, please.
I edited my post for length (not substance) before your response appeared. I kind of regret doing that now, as I was trying with my edit to be conciliatory and understanding of your confusion. Here is what was edited:
I have never used the ‘Ignore’ user feature before, but I am close to putting you on ‘iggy,’ as I find your posts annoying in their frequency and their frequent inaccuracies. I am sorry it has come to this, but I felt something needed to be said.

Thank you stevem2! I am reading about Bit Perfect now. It sounds like it is to be used with iTunes. I am not using iTunes on my Mac mini. Roon is locating and playing the DSD files. Can Bit Perfect be configured without using iTunes?
We have an ignore feature here??!!! Where?
EDIT: Oh my god! I just found it! Hooray!
2nd EDIT: Rats, I see I have already used it and it doesn’t appear to work. Sigh.

I’m gonna start by saying, this is what I do and works for me for now on…but this is what works for me…again, since it sounds like you’re using a mac(like me).
You can play .dsf files and send them directly to your matrix using a USB. Again, you can not send .dsf files directly to your DSD Sr by usb.
Personally, I like using itunes because I like to sort/organize my DSD64 music all in itunes on my mac. Again this is a personal preference…everyone relax.
To do this I use a program called ‘DSD Master’. You can read about it here:
You need to also use a program called ‘bitperfect’ in concert with these .m4a files(which DSD Master creates) to play them with itunes…but when you do so your DSD Sr will display ‘Input DOP Rate DSD 64/128 etc’. This works with the matrix or without it.
Imo, the sound is excellent doing it this way…
Again that is just what works for me…everyone relax…there are multiple ways to do the same thing.
Hope that helps.

Thank you speed-racer! When I set the volume control to “Fixed Volume” there is no sound. I only get sound when it is set to “DSP Volume”.
Say what?
Buh bye. . .

You can’t send native DSD files directly to the DSD Sr through USB.
