pacmd – Reconfigure a PulseAudio sound server during runtime
This tool can be used to introspect or reconfigure a running PulseAudio
sound server during runtime. It connects to the sound server and offers
a simple live shell that can be used to enter the commands also under‐
stood in the default.pa configuration scripts.
To exit the live shell, use ctrl+d. Note that the ‘exit’ command inside
the shell will tell the PulseAudio daemon itself to shutdown!
If any arguments are passed on the command line, they will be passed
into the live shell which will process the command and exit.
