Class SetPlayoutDeviceRequest

Namespace

LiveKit.Proto

Set the playout device (speaker/headphones).

Call this before connecting to select which speaker to use for audio output. Use the GUID from AudioDeviceInfo for stable device selection across hot-plug events.

Platform Notes

• Desktop: Works as expected - selects from enumerated devices.
• Mobile (iOS/Android): No-op. Mobile platforms handle audio routing at the system level. This will succeed but has no effect. For audio routing on mobile:
  • iOS: Use AVAudioSession to control speaker/earpiece/Bluetooth routing
  • Android: Use AudioManager.setSpeakerphoneOn() to switch outputs
