Minimserver sample rate stuck at WAV/48kHz/16 bits/stereo

Now lately, when I play the same 192kHz flac files, the BubbleUPnP app shows FFmpeg:WAV/48kHz/16 bits/stereo. My dac also shows WAV/48kHz/16 bits.
It doesn't matter what type of files and sample rate I play, the BubbleUPnP shows FFmpeg:WAV/48kHz/16 bits/stereo. It seem my miniserver is stuck at FFmpeg:WAV/48kHz/16 bits/stereo.

I tried deleting all my stream.transcode and putting "none" in stream.converter. Still the same.
What is going on? Please help Simon.

That's not caused by MinimServer, but by BubbleUPnP new feature introduced in v2.9 that can decode audio to PCM (similar to MinimStreamer PCM decoding features), either to be able to play unsupported audio formats by the renderer, or to enforce 'max supported samplerate', '16 bit' or stereo for renderers that need it. It can also do ReplayGain. Except for a few known renderers, the defaults are super conservative with a max of 48 kHz / 16 bits / stereo that is guaranteed to play on all renderers.

To change these defaults:

- go to Settings > Individual UPnP/DLNA renderers settings > (pick your renderer in the list)
- set 'Max Samplerate' to unlimited (or 192 kHz)
- disable 'Convert 24-bit to 16-bit'
- if you want multichannel audio unmodified, disable 'Downmix multichannel to stereo'
