Start cinelerra-gg from terminal so you can see terminal output

Open your source in cinelerra-gg as usual, choice format settings, go
to DVD creation  window.

Select all values as you need, click ok, wait for batchrender window to appear

In it, select second line and change codec to RAW PCM, and set it to
16 bit, signed, byteorder Lo-Hi (big endian)

click "start". Cingg will finish but job is not!

from terminal, note location of dvd.sh file and open it in editor

running /dev/shm//dvd_20240116-182336/dvd.sh
   INFO: [mplex] mplex version 2.1.0 (2.2.7 $Date: 2012/11/17 01:55:16 $)
**ERROR: [mplex] Unable to open file
/dev/shm/dvd_20240116-182336/dvd.ac3 for reading.


mcedit /dev/shm//dvd_20240116-182336/dvd.sh

and set mplex parameter " -L  48000:2:16" so full string will look like

mplex -f 8 -L  48000:2:16 -o $dir/dvd.mpg $dir/dvd.m2v $dir/dvd.lpcm

note, lpcm extension is important!

now mv pcm file into same but with new extension  (in theory you can
change audio file extension into lpcm at batchrender window, not

 mv /dev/shm//dvd_20240116-182336/dvd.pcm /dev/shm//dvd_20240116-182336/dvd.lpcm

run script:

you probably need to tweak dvdauthor file to so our  audio will be
audio channel 0.

I'm thinking about making "use PCM" checkbox in (already a bit
crowded) DVD creation window ..lets see now it will progress ...
