如何查看 Android 设备是否支持杜比数字？

Question

Is there an API on android to check if a device supports DolbyDigtal(AC3) ?

Is there any other way, besides using AudioManager.getReportedSurroundFormats() (which isn't listed in the official documentation ?

Answer 1

Refer to documentation that audio format for Dolby Digital is AudioFormat.ENCODING_AC3 . So you can check Dolby Digital supported from available audio output in your device like this.

val audioManager: AudioManager = /* ... */
val audioDeviceInfos = audioManager.getDevices(AudioManager.GET_DEVICES_OUTPUTS)
    .filter { it.encodings.contains(AudioFormat.ENCODING_AC3) }
