      Getting Epson EF-12 to output Digital Surround Sound<\/h2>\n

      To get 5.1 digital surround sound to an AV receiver over ARC from an Epson EF-12 Android TV, the above settings were what I needed to use.<\/p>\n

      Below are the caveats & explanations of why the these settings work.<\/p>\n

      According to Kodi engineers, HDMI ARC can only output two channels of audio data<\/a>. That’s why we set “Number of channels” to 2.0.<\/p>\n

      If Output configuration is not “Optimized”, only two track stereo will be passed through.<\/p>\n

      By default, the Passthrough output device is\u00a0Kodi IEC packer.\u00a0 This will not work.\u00a0 It must be set to AudioTrack (RAW), Android IEC packer as Android is mixing down the audio data into 2 channels for output over ARC, which only supports 2 audio channels.\u00a0 This doesn’t mean we’re only sending Left and Right audio channels.\u00a0 It just means we’re sending the encoded bitstream<\/strong> of 5-channel Dolby Digital data over one of these two channels<\/strong>.<\/p>\n

      “Dolby Digital (AC3) capable receiver” tells Kodi to output raw encoded Dolby Digital bitstream and that the device (your AV receiver) on the other end will perform the decoding.<\/p>\n

      “Enable Dolby Digital (AC3) transcoding”\u00a0 will transcode DTS sound data into Dolby Digital AC3 for transport over the ARC audio channels.\u00a0 Kodi, on Epson Android TV systems, does not currently support raw DTS audio data over ARC\u00a0(as of Kodi 19.3 Matrix).\u00a0 This is why we need Dolby Digital transcoding ON: we’re converting DTS into Dolby Digital AC3 5.1 signal<\/strong>.<\/p>\n

      “DTS capable receiver” OFF will force transcoding<\/em> of DTS streams into DD AC3 streams since Kodi on Epson Android TV does not support DTS passthrough over ARC at this time.<\/p>\n

      So the big caveat with all this is: DTS cannot be directly output \/ passthrough as-is to your DTS receiver.\u00a0 It must be transcoded from DTS into Dolby Digital.\u00a0 It’ll still be 5.1 digital surround at least.<\/p>\n

      Also, Kodi on this Epson Android TV hardware cannot output anything but basic Dolby Digital AC3 5.1.\u00a0 So no DTS HD, Dolby True HD, no E-AC3 nor Atmos.\u00a0 Just basic Dolby Digital AC3 5.1.<\/p>\n","protected":false},"excerpt":{"rendered":"
