Audio integration is adding sound to what plays on a screen. Technically it is straightforward: the panel has speakers, the player outputs audio, the content carries a track.
There are places it belongs. A single-viewer kiosk with a directional speaker, a waiting room where the screen is the only thing happening, a demonstration a customer chose to start. The common thread is that the listener opted in, or is alone.
The caveat is that in a shared space, sound is the fastest way to make staff disable a screen. People working near a display hear the loop hundreds of times a day, and the reliable outcome is the volume turned to zero or the unit switched off at the wall, which is how a network loses screens without anyone reporting a fault.
Design so that content works silently by default. Captions rather than voiceover, and if audio matters, trigger it from an interaction or use a directional speaker that confines it to one standing position. Sound that plays unprompted into a room is nearly always a mistake, however good the content is.
