In that case CamillaDSP does no volume attenuation, and does all other processing at 0.0 dB. Before the PCM “enters” CamillaDSP it is up to the renderer to control the volume.
Because CamillaDSP is a plug-in to Alsa and not an output device, it offers no Alsa mixer itself.
I don't think Camilla is an ALSA plugin (LADSPA) but rather a standalone application that does DSP. On Linux it's fed by an ALSA output plugin named alsa-cdsp. My understanding is that its purpose is to automatically configure the correct source sample rate in Camilla when song files of varying sample rates are being played.
I'm still a bit confused about volume handling though because Camilla can do things like EQ which manipulates volume and the Pipeline editor also has a volume Mixer tab.
