How do we register custom plugin with LMS the correct way?
On RPi / Debian I saved MyCustomConvert plugin in
Code:
/var/lib/squeezeboxserver/cache/InstalledPlugins/Plugins/MyCustomConvert
then restarted LMS from console window
Code:
Thanks!

Final test to exclude the flac application from the equation.
Code:
flac -dcs --force-raw-format --endian=little --sign=signed srv.flac >
srvPIPE.pcm
ffmpeg -f s16le -ar 44.1k -ac 2 -i srvPIPE.pcm srvPIPE.wav
Here we use the same command

I've seen similar from HiFi Berry S/PDIF where there are some -3 dB.
That could

I'm on latest

Yes, we can also have it in user home directory under another name. See
the description on the that page.

Try these
@slartibartfast
As before mentiod I installed Squeezelite from the package manager with
output to 'default'.
~$ sudo apt install squeezelte
Output in the asound.conf use name of you sound card. Or simply try
'card 1'.
Code:
pcm.output {
type hw
card

Quite possible, if a problem at all. I where lead in a direction due to
how the WAV file repeatedly got 100% match while the FLAC always failed
when recaptured multiple times. With now a more a extended dataset using
different input
Thanks @bpa. More to digest. The tee command can prove useful to compare
Ogg/FLAC stream to ffmpeg capture at alsa output. Ahh of course,
directing the convertion to an application of own making opens up many
possibilities. Thanks, inspires to think of new ways of using LMS.
With data

No, that's not necessary. Don't even have to be the same bit depth,
format or amplitude. DW will convert, seek and find start position on
its own. And then try to even out levels and clock

When capturing S/PDIF or analog out whatever medium used will be hard to
compare. I've tried. Only usefull data I found is the clock and jitter
difference. And even that might not be of interest using a modern DAC.
I duplicate

Thats what DeltaWave are for I think ;)
Fact is I can repeatedly capture a bit perfect stream from WAV files.
LMS use 'flac -d' output to stdout.
I wonder if someone can confirm I have the correct understanding of this
configuration?
What I want is to trancode FLAC to PCM on server side. My unsertenty
stems from Material Skin still says its streaming flac and actual output
is the same as with the native setting. For now I just need to be
Thank you. If you are able to see my screen dump in my first post that
show my interpretation of that setting.
And I also conclude from the log that the stream is transcodet on the
server.
Reason for me to be absolutely sure are for troubleshooting another
problem.
Messing around with Deltawave https://deltaw.org/ I found that capturing
Alsa output from Squeezelite on RPi-OS I have absolutely bit perfect
output from Squeezelite if streaming WAV files from local network.
Sadly results from streaming FLAC where not as joyful and comply with
listening
