Asset UPnP and PC Sound capture (WASAPI)

[AndersHansson]

I have a setup with asset UPnP as server (on windows 10) and using Bubble UPnP as control to a Raspberry Pi 3 with Moode as audio renderer.

I have tried to force the asset UPnP not to transcode into MP3 by override but I just end up with LPCM at 44.1kHz sample freq. How should I configure the Asset UPNP to handle 24bit/96khz audio via WASAPI?

I have also tried with WASAPI setting "as is" and windows settings to 24bit/96kHz. And this setting correspond to the source material played. With this setting I get 24bit/44.1kHz and 320kbps (MP3). Any ideas on how to get 96kHz through?

WASAPI is always captured at CD quality.

Oh.. I thought WASAPI could be used without re-sampling. It would have been really nice to be able to stream high quality audio using WASAPI. Any alternative suggestions?

It is not possible to do as you describe, for example you play CD quality track, then the next track is 24 bit 192KHz, the audio capture at that point would have to stop, and restart using the new values, except the player in the UPnP chain cannot accept a new audio capture, it can only have one continuous playback.
