you could use a null-sink instead of alsa-sink.1 in combine-sink and
then null.monitor as source for
null-sink.monitor -> module_loopback -> alsa-sink.1 -> front speaker
Or you could even play back your original audio to a null-sink and use
it's monitor as
input for both, processed and non-processed audio path. This would
setup and you would not need alsa-sink.0 and alsa-source.0 at all.
