[Cin] sox to lpcm

[Andrew Randrianasulu]

command line:

sox  /dev/shm/dvd_20240120-153459/dvd.wav -V -t raw -x
/dev/shm/dvd_20240120-153459/dvd-1.lpcm

I set output file to different name so I can compare pcm directly
produced by cingg and sox-converted version.

detailed output:

sox  /dev/shm/dvd_20240120-153459/dvd.wav -V -t raw -x

=====

so, modern sox (-w/-s options were deprecated and replaced by others -
thankfully we do not need them if input file autodetected) can process
wav files into lpcm suitable for mplex

So, guide is much simpler in sense in cingg you just change audio to
wav/24 bits, then run sox, and change mplex line to one including -L
freq:channels:bits specification. May be you can even prepare text
patch and apply it to dvd.sh ?

 Oh, and in case of 24-bit audio at 48 khz you definitely want to
lower your video bitrate ...
