This page contains the options and settings to ensure your audio device functions correctly with Kodi. The settings chosen here can have a big impact on CPU load on lower powered hardware, so it is worth the time to understand the available options and how they should be configured.

The options shown in the images are from a Windows 10 HTPC and may differ from other hardware platforms. Some options change depending on whether an WASAPI or Direct Sound driver is selected in the Output selector.

If this is your first time adjusting the Audio Settings you may like to use the Audio Quick Start Guide.

3 Audio Passthrough

When playing a movie or tv show, Kodi will decode the audio stream and send the audio to the respective channels and speakers. When using Audio Passthrough, Kodi does not decode the audio stream, rather it will send the original audio stream to the AV Receiver to be decoded by the Receiver.

To use this option, you must have passthrough capable hardware and an AV Receiver capable of decoding some or all of the formats listed below. Formats that the Receiver cannot decode will be decoded by the Kodi Audio Output Decoder.

If you have a quality AV Receiver, Audio Passthrough should be used.

Do not enable a codec type in the capable receiver section if the AV Receiver does not support that codec. Doing so will result in poor playback of video typically with very low frames-per-second video and no audio. For example enabling TrueHD capable receiver option on an older receiver that does not support this audio codec.

If connected directly to a TV be aware that TV's are not compatible with DTS, TrueHD or DTS-HD. Typically AC3 is the only encoded format a TV will be compatible with.

3.1 Allow Passthrough

Settings level: Standard
Description: Select to allow passthrough audio for playback of compressed audio such as Dolby Digital (AC3), DTS, etc. The Client of the AudioEngine might decide to decode the audio stream under certain conditions.

Note: When the setting Sync Playback to Display is enabled, it will disable Passthrough. Both settings cannot be enabled at the same time.

3.2 Passthrough output device

Settings level: Standard
Description: Select the device to be used for passthrough of the encoded formats. Windows users must use WASAPI. Passthrough is not available for DirectSound.

The following codecs can be passed through and should be set in accordance with the capabilities of the AV Receiver:

  • Dolby Digital (AC3) capable Receiver
  • Dolby Digital Plus (E-AC3) capable Receiver
  • DTS capable receiver
  • TrueHD capable receiver
  • DTS-HD capable receiver
