1662 If the LADSPA plugin has multiple audio inputs or outputs the policy duplicate
1665 The plugin serialization works as expected. You can eventually use more
1666 channels (inputs / outputs) inside the LADPSA plugin chain than processed
1667 in the ALSA plugin chain. If ALSA channel does not exist for given LADSPA
1669 side (ALSA next plugin input), the valid channels are checked, too.
