Controller speaker
The controller has a small speaker and a headphone jack. Adaptive Pad adds a DualSense Speaker audio endpoint to Unreal: any sound sent to a submix of that type plays on the controller instead of the PC's speakers.
Set it up
Create the submix
In the Content Browser: Add → Audio → Mix → Sound Submix Endpoint. Open it and set Endpoint Type to DualSense Speaker.
In Endpoint Settings pick DualSense Speaker Settings to choose the controller (Controller Id, 0–3) and an extra Gain.
Without settings it plays on the first controller.
Send sounds to it
On a Sound Wave, Sound Cue or MetaSound, set Base Submix (in the Effects section) to your new submix. Use a Submix Send instead to play a sound on both the PC and the controller.
Keep these sounds 2D (no attenuation or spatialization): the speaker is mono and sits in the player's hands.
Play it
Play the sound as usual, for example with Play Sound 2D or an Audio Component.
Speaker or headphones
With nothing in the jack the sound plays on the speaker, mixed to mono. Plug headphones into the controller and it switches to them automatically, in stereo. DS Are Headphones Connected tells you which one is in use.
DS Set Audio Volume sets the speaker and headphone volumes (0–1, default 1). Like the other output nodes, apply it with
DS Update Output.
Good uses
- Short, close sounds: a radio, a reload click, a "ding" for a pickup, footsteps of a companion talking to the player.
- Feedback that matches the haptics: the same event felt in the hands and heard from them.
- Leave music and the main mix on the PC: the speaker is small and quiet.
