lovr.audio.setDevice
EditSwitches either the playback or capture device to a new one.
If a device for the given type is already active, it will be stopped and destroyed. The new device will not be started automatically, use lovr.audio.start
to start it.
A device id (previously retrieved using lovr.audio.getDevices
) can be given to use a specific audio device, or nil
can be used for the id to use the default audio device.
A sink can be also be provided when changing the device. A sink is an audio stream (Sound
object with a stream
type) that will receive all audio samples played (for playback) or all audio samples captured (for capture). When an audio device with a sink is started, be sure to periodically call Sound:read
on the sink to read audio samples from it, otherwise it will overflow and discard old data. The sink can have any format, data will be converted as needed. Using a sink for the playback device will reduce performance, but this isn't the case for capture devices.
Audio devices can be started in shared
or exclusive
mode. Exclusive devices may have lower latency than shared devices, but there's a higher chance that requesting exclusive access to an audio device will fail (either because it isn't supported or allowed). One strategy is to first try the device in exclusive mode, switching to shared if it doesn't work.
