“Owners manual states that the HDMI Arc socket outputs 5.1 sound. I can't get 5.1 from the built in Prime Video app via the HDMI Arc socket to my AV Reciever. Why does the manual say Arc socket outputs 5.1 sound when it doesn't? Is the owners manual wrong?”

Amazon Prime Video uses AC-3 5.1 Codec on the app, so that's not the problem. None of the built in apps within the EH-LS300s Android 9 tv output AC-3 5.1 surround. Even Google Play movies and tv app uses AC-3 5.1 Codec and that's not outputting 5.1 either. Selecting either Auto or pcm within the Android 9 tv sound settings only outputs 2.0 pcm for all apps via the HDMI 2 Arc to external speakers. Arc is also selected in the EH-LS300s Projector settings. Using external devices plugged directly into my external speakers gives me AC-3 5.1 sound from all the supported apps including the ones i've mentioned that aren't outputting AC-3 5.1 on the EH-LS300. So when all the apps use a 5.1 AC-3 Codec and the EH-LS300 outputs only 2.0pcm then there is something either wrong with the EH-LS300 or the owners manual is stating something that's not correct as the owner's manual clearly states that the Arc socket outputs AC-3 5.1 sound.
Sorry, there was a problem. Please try again later.Hello HobbyAV. The LS300 Projector does support 5.1 Audio output. For the output audio to work, the content you are watching must be using either an AC-3 or DTS codec. The application may be using an unsupported codec, in which case the 5.1 audio will not correctly work. We recommend selecting PCM under the "Sound output format" option in the projector's menu if you cannot hear sound through your external speakers properly. Regards, Kevin - The Epson Team.
