No AOA sounds

Just completed my first 5 hours of flying my RV-12iS going through all the required testing. Everything worked great with one exception. My AOA has no sound. I have done the calibration twice. The chevrons are present and work as expected but there is no sound. I temporarily disabled the stall horn just to make sure it was not overriding the AOA but still no sounds. Sent a question to Dynon and they were surprised the RV-12 even had an AOA so not much help there. Volume for the AOA is set to 100%. Anyone have ideas on what to check now?

Check and see how it is tied into the intercom. I seem to remember that it must be connected to the "music" input. It's been quite a number of years so I may be remembering wrong. (It's happened before!)
 
Maybe count your blessings instead. Friend's RV-12 with dual HDX and AOA. Both stall warning and AOA blaring away on each landing. Yeah, it works, but you get numb to the whole thing pretty quickly...

Perhaps they are not configured right?
 
Below is copied from the SkyView System Installation Guide – Revision AJ page 4-34 and 4-35
SkyView Audio Output Settings
Go to SETUP MENU > SYSTEM SETUP > AUDIO SETUP to configure audio output settings. Most of the items in this menu control whether the audio output for a particular alert or alert category is played or not.
ANGLE OF ATTACK – This sets a pulsing, progressive tone that increases in frequency, similar in nature to a conventional reed type aircraft stall warning sound, although it is much more predictable in its progression. It can be set to start its pulsing tones at either the border of the yellow/green marks on the AOA bars, the middle of the yellow, or the yellow/red border. The pulsing tones start at the level selected and get progressively quicker and closer together until a solid tone is played at critical AOA (in the red.)
INHIBIT AOA BELOW AIRSPEED – Allows you to set an airspeed below which no AOA tones are played. This helps prevent nuisance alarms while on the ground and taxiing . . .
Below by Joe
Set the AOA sound to just start pulsing slowly when the aircraft is "ON SPEED" during final approach.
