# Set up LPCM and Dolby-E pass-through

LPCM and Dolby-E inputs on SDI can be passed through and carried on the TS as SMPTE-302 and Dolby-E respectively by selecting the **SMPTE-302 / Dolby E Pass-Through** codec from Live Encoder **Encoding** > **Audio encoding** section (see [Configure the audio encoding parameters](/beam/live-encoder/configure/encoding/audio-encoding)).
