[FFmpeg-user] Transcode 5.1 Flac to 5.1 LPCM in ffmpeg

Here is the printout. You said ffmpeg doesn't support encoding Bluray PCM,
but there seems to be such codec included below? Which codec should I
choose to transcode 5.1 Flac to 5.1 LPCM audio in ffmpeg, and how the
command line would look like?
If none, what these PCM codecs are for - any link with description? What
other program would someone suggest for the task? I tried eac3to, but the
resulting file can't play on any player supporting LPCM playback like Daum
Potplayer or VLC, despite it can be imported and play correctly in
Audacity. Probably, the header is wrong. FFPlay says: "Invalid data found
when processing input".
Also, what media info program can decipher media info from multichannel
LPCM file? I tried MediaInfo and Gspot with no success. FFMpeg -i gives
the same above error.
