LADSPA - not finding ACDf

Is anyone running Charlie's ACDf LADSPA filters on Raspberry Pi OS 11 (Bullseye) 64 bit?

I'm running the identical asound file that worked on Stretch, but am now getting "Unable to find or load plugin ACDf" despite ACDf.so being in the appropriate folder.

In hope, Andy
 
If you installed a new OS, or even possibly with an update, you might need to check to see if the LADSPA_PATH variable is (still) declared properly. I usually add that line to the .profile file in your home directory (I suggest this location in the ACDf README file). Without that defined programs do not know where to look for any LADSPA stuff.

One easy way to check to see if LADSPA plugins can be found is to run the command:
Bash:
listplugins

This should return a list of the plugins that are currently installed. LADSPA-SDK installs a few by default, and you should also see ACDf listed (usually first in the list).
 
Thank you, Charlie, for reminding me to rtfm🙂. That sorted it.

Sadly, Bullseye seems to have an aversion to my asound file; flac files can be played to each output at the "aplay -D hw:0,0" level, but alsa collapses when it has something more complicated to do.

Back to building asound from the ground up again.
