+#### Audio

+==-  :icon-unmute: Audio Passthrough Configuration
+You can have MPV passthrough proprietary codecs, however this requires you to have a supported sound system. If you have a soundbar/reciever with Dolby or DTS support, read on.
+If you have a system that supports both, and is connected via HDMI, you should be able to uncomment the two lines and make no other changes.
+!!!warning
+When using eARC, both the sound system and TV need to support the codec you are trying to pass through. If one of them is lacking a codec, you will not be able to pass that codec through. If your system has HDMI ports, you can directly connect your computer to it instead of using eARC, otherwise the codec will be converted to PCM.
+!!!
+If your sound system uses SPDIF/Toslink/Optical, remove the `,dts-hd,truehd` from the first line, and the `,7.1` from the second line. This is because these formats are not supported via an Optical cable.
+!!!
+Note that removing dts-hd and truehd from the config will not prevent them from being picked. DTS-HD should automatically play the compatibility track, however TrueHD will be transcoded to PCM. The trackselect.lua script can be used to exclude TrueHD, which should automatically pick the compatibility track instead.

 #### Scripts
 
 Most modern TVs are capable of changing refresh rate to match the frame rate of the content, which removes [judder](/guides/playback#explaining-judder).
