Do you really want to convert PCM (i.e. FLAC) files to DSD and send them to your DLNA Renderer via DoP?
Is the sound quality so much better, even though you are doing a conversion in the process?
Is there some other reason you want to only send DSD DoP to your Renderer, such as track transitions, your Renderer doesn't switch between PCM and DSD DoP reliably, or something else?
EDIT: Maybe for the reason documented here:
https://yabb.jriver.com/interact/index.php/topic,121168.0.htmlIf there is no good reason, consider just playing the original format, as you described in the first post, and enjoy the music!
1. The pre-defined "Generic DLNA" and "Audiophile 24-bit DAC" DLNA server definitions are just templates. You can add either one, then rename it and change settings to make them do whatever you want. Compare the settings and you will see this.
2. I don't have a DoP capable DLNA Renderer or do what you are trying to do, but as you want to use DSD DoP, which requires access to the DSP Studio under DLNA settings, you need to choose a format. If your source files are rips from a CD to FLAC, then either "PCM L16 No Header" or "PCM 16-bit" would make most sense, as the source would be 44.1KHz 16 bit PCM. There would be less, or no conversion in that case. If any expert wants to comment, cool.
If you only want to convert certain file formats to DSD DoP, then use the "Specified output format only when necessary" setting, and then list the file types that you want to convert. FLAC if these are files creating by ripping CDs to the FLAC format.
3. Parameters in DSP Studio? Just select the output encoding as "DSD in DoP format". Or "2xDSD in DoP format" or "4xDSD in DoP format", depending what your Renderer supports.
Note that if you are doing the above, MC will decode the FLAC files to PCM, hopefully without any conversion, and then encode them as DSD in DoP. Potentially a double conversion, and in some people's opinion, not worth it. Hence my questions at the beginning of this post.
- if I set
- Audio > Mode: Specified output format and
- Audio > Format: PCM 16-bit / PCM 24-bit / PCM L16 no header / PCM L24 no header
=> MC25 reports "There was a problem controlling the selected DLNA ..."
Implies that your Renderer doesn't support the formats you selected. You should run AndrewFG's Digital Media Renderer Analyser to find out what you Renderer supports. Search for forum user AndrewFG and find a link to his DRMA in his signature.
However, that error could also indicate other DLNA issues, because PCM L16 No Header should always work.
- if I set
- Audio > Format: MP3 medium / high bandwith
- Audio> Advanced> ... DSP Studio ... no changes
=> the reproduction works unchanged
Good. So your Renderer can play MP3 files, and the connection and control works.
if I set
- Audio > Format: MP3 medium / high bandwith
- Audio> Advanced> ... DSP Studio ... change from PCM 44.1 to 88.2
=> the renderer receives a data flow PCM 48.0 ? Why?
MPEG-1 Audio Layer III (MP3) only supports up to a 48KHz Sample Rate. So naturally, MC can't output an MP3 with an 88.2KHz Sample Rate. See "Supported sampling rates" here:
https://en.m.wikipedia.org/wiki/MP3- if I set Output encoding "DSD in DoP format"
=> the renderer receives a data flow PCM 48.0 again ?
Same as above, if you left the output format on one of the MP3 settings. MC is first converting to MP3 format, and it can only output 48KHz files. Why that isn't then converted to DSD DoP I don't know. But change the output format to "PCM L16 No Header" and see if MC will convert to DSD DoP then.
By the way, the manuals for the "Pro-Ject Stream Box s2 ultra" only say that the unit supports up to DSD256. It doesn't say if it supports DSD DoP (DSD over PCM) or Native DSD. You may wish to check with Pro-ject what it actually supports, and test with AndrewFGs DRMA, as above. You could also just try to output Native DSD. When you successfully played DSD64 and DSD128 files, did you output them as DSD DoP or Native? It sounds like it was Native. In which case, select one of the Native DSD formats in DSP Studio.
