aconnect Command in Linux with Examples

aconnect command is used to connect two ports on the ALSA sequencer system.  ALSA (Advanced Linux Sound Architecture) is a framework which is part of the Linux kernel that provides an API for sound card device drivers and the ALSA sequencer interface is designed to deliver MIDI-like events between clients and ports.

Syntax:

aconnect [-d] [-options] sender receiver
aconnect -i|-o [-options]
aconnect -x

Example:

aconnect  0:0 14:0

The above example connects port 0:0(sender) to port 14:0(receiver) and the flow of data is one-way. Multiple receivers can be attached to one single sender.  No output is displayed for this particular command.
