Can't play flc files

[ProteinPig]

I have installed Mobile Transcode, and lms docker method installed.
When I try to play flac files, the stream stoped, and the logs show below:
/lms/Bin/x86_64-linux/sox FAIL sox: `-' error writing output file: Broken pipe
But when I switch to mp3 which use lame, everything goes ok.

I try play the same flac files with iPeng, or other squeezelite based player on Android, It's OK too.

When I say "switch to mp3", I mean choose Compressed (MP3 preffed) instead of Lossless FLAC) in LyrPlay.
Then play the same file.

Odd - what do you have bitrate limit set to? Did you try restart server / app?

What are you transcoding?

I have restarted LMS and LyrPlay multiple times. Below are my app settings and the plugins enabled in LMS. Additionally, I am using the sample1.flac file downloaded from https://filesamples.com/formats/flac as an example.
