Streaming HD audio distorted [Solved]

(1/6) > >>

dpfels:
Hi,
I am attempting to stream audio from my UPNP/DNLA server to Media Center 30 for Mac with weird results.  The music plays at the wrong speed (too fast) and with a lot of distortion. This is true for multiple file formats, including, particularly,HD (high bit rate) FLAC files.
I suspect that there is a problem either with the way Media Center is interpreting my audio files or the way that it is sending it to my DAC (a FocusRite Clarett 8Pre).
I have tested the Clarett with other streaming/audio software, including iTunes and music software including Ableton Live and iZotope RX (playing the exact same files) with no issues.
Is this an issue with the Media Center or a problem with the default settings?  If it is the settings, can someone point me to the right settings page to fix this?
Thanks,
Dan

So MC is the Renderer and you're sending to it from other software?

In certain cases, MC will convert if it's the DLNA Server and you can change that in Media Network settings.

What type of files are you starting with?  Do ordinary FLAC files work?

More details might help.

I will do my best to answer.
Files are high def FLAC (192kHz · 24bit or similar), although I have tried this on lower bit-rate files, they are mostly FLAC.  I will try again with other flavors of files, including lower bit rate (44.1/16bit CD rips or MP3 files, both of which are common in my collection), but I am certain that all files I tested had an issue.
File server is a Synology NAS (DS214play) running their own DLNA server software.  I have also tried it with minimserver running on the same NAS device.  I am able to stream music from this server to a streaming box (from Cambridge Audio) or to an I)S device (using a variety of apps to stream) with no issues.

I assume that MC is attempting to transcode/convert the files (incorrectly).  The other possibility is that MC doesn’t like my DAC (again, my focusrite Clarett works fine with all other MacOS software so far.

Please let me know if I can provide other details.
Thanks,
Dan

I'm confused about your setup.  Do you have files imported into MC?  Or are you using some DLNA "server" and only using MC as a renderer?

MC does really as the library source.  Meaning that you have files imported into MC and MC plays them.  As a renderer being controlled by 3rd party tools, I'm not sure.

My recommendation would be to use MC directly.

Sorry for the confusion.
I am using MC as a “renderer”, although that is not the word I would have used (i was thinking it is a DLNA client for a remote server,  but I think that is the same thing).

I will try importing a few files directly into MC to see if it is any better.  However, I note that MC has a feature for connecting to a remote DLNA server/source, which is what I have been using.  MC has no problem selecting and playing files, which suggests that it complies with that part of the DLNA protocol.  It’s just an issue with the sound quality of the streamed music.

I had been hoping to use my Mac as an audio streamer, since my files are all stored on a remote network attached file server.  The benefit here is that the server software keeps my files or organized in the same way independent of where I am streaming.

Again, I will try this with a file that has been loaded directly into the MC library and see if it is any better.  May not have a response until later tonight.
Thanks,
Dan
