flac24 transcode incorrectly
Hello,
Yesterday I tried to use transcoding .flac files on minimserver to .wav file to feed my Raspberry Pi. I use minimserver update 101.

I followed the guide and used the code "flac(24):wav24, flac(16):wav16".
Only 16-bit flac files works as expected (be transcoded to 16-bit wav). All of my 24-bit flac files are transcoded to 32-bit wav.Sad

How can I get 24bit wav with transcoding from 24bit flac?
Thanks in advance
trung

Your current settings should transcode 24-bit FLAC to 24-bit WAV. However, to get what you want, it is simpler to just specify flac:wav.

I tried what you said but after transcoding, 24-bit FLAC still become 32-bit wav,
16-bit flac works fine

Have you double checked with something other than the Moode Audio Player's own Audio Information display, as that may be reporting incorrectly?
For example, what does the Linn Kinsky controller you are using report the transcoded file's resolution as (right click the file track & select Details from the menu)?

I have check with Volumio, but the result is still the same. So I suspect that the problem lies on the wav-transcoding built-in on minimserver.Huh

I hope Simon could check the source code and provide some insight.

I think the reason for this is that your hardware can only play 16-bit or 32-bit WAV. MinimServer is sending the audio as 24-bit but something in the ALSA stack is converting it to 32-bit to match the hardware capability.
