DoP is transported as a 176.4/24 PCM format, but the 24-bit PCM-frames contain an 8-bit DSD marker (MSB) (consisting alternately of 0x05 and 0xFA indicating each of the two channels) and 16-bit DSD-data.
Is this document making things sufficiently clear for you?

so a 176.4/24 version is going to do the job ?
As long as mqn accepts this construction of PCM-frames, i.e. not filtering out or rejecting the data because it is constructed with these markers.
I have other players playing DoP just fine and interpreting the stream just as a 176.4/24 datastream and let it pass it through without modification.
The DoP capable DAC will do the decoding as it recognises the construction of the PCM-frames as DoP.

I see DJ le Roi has all flavours working including 24/88, is there a corrected version of 24/88 somewhere that I missed ?
think he must be imagining things
Your comments made me a little bit insecure so I tried again all bitrate versions.
And, I can't help it but they are really working.
By the way: I use MQNLoad. I do not use Tasker. When I choose a 24/88 song, I choose mqnplay.exe 2488 24 bit 7.41 avx2. When I choose a 24/192 song, I choose mqnplay.exe 24192 24 bit 7.41 avx2.
I use 3.64 and PA84 AVX2. PA86 AVX2 is also working.
I have a AMD A4-5300 processor (which officially doesn't support AVX2).

Thanks for that DJ, sorry for troubling you. I'm oldfashioned and simply use MQNbat , no loader or tasker so I just need a corrected version of 24/88 that has the missing line included.

My assumption with my previous comments, is that the stream has been already encoded in DoP format outside of the mqn-player.
If you want to encode the original DSD as DoP yourself, then it is a different matter altogether. Then you will have to create the DoP-encoded frames.
But based on my assumption of pre-encoding into DoP using another program, mqn can just send it on as a 176.4/24 PCM and you/mqn doesn't have to confirm anything with the device or its driver as it being a DoP or not, the DAC will detect that by itself. You/mqn just offer it to the device as being a genuine 176.4/24 PCM-stream.
