Ed, (Inserting my opinion rudely)

An example would be the alert sounds played by YAAC when APRS messages are received or emergency beacons are detected, etc.  In my case I route that audio out to HDMI to be played out on the monitor speakers.

Thank you. So this for getting the System Sounds out to the speak so one can hear the OS sounds or program sounds that are sent to the OS for user interaction, correct?

The RPI has two native audio output sources on it. Those would be:

#1 3.5mm Headphone Jack.
#2) HDMI Port

You do not want to send standard auto prompt tones out the DRAWs TI audio chip set. So you would want to send them out a different audio interface line the headphone of HDMI jacks.

practical application stand point?
