So, are you telling us that ALSA inserts the plugin in

doesn't work that way at all.
the app opens "plughw:ladspa" (for example) for playback. presto: the
ladspa plugin is applied to the playback stream.
the app opens "hw:0" (for example) for capture. no plugin processing
on the capture stream.

remember that there is no such thing as a duplex ALSA stream (similar
to several other audio device APIs).
If the ALSA device doesn't provide enough level on
the mic
input then there is something wrong with either the driver
or its configuration.
agreed.
