I'm asking you because i'm a new owner and i'm thinking about buy a new AVR with eARC but in few thread/forum and also on sony's website
The audio lossless content via internal apps (USB et al) in not sent via earc. The built in speakers ad far as i know could reproduce it by decoding it (as LG C9 does) but cannot send bitstream via eARC).
What i can tell is i have tested a 4k hdr rip containing the truehd audio codec loaded onto a WD external hdd hooked to the a9g usb port on the back and it did work on the eARC downstream signal. I cannot say with dts master audio or uncompressed LPCM as those i haven't personally tested. For making truehd bitstream work, i had to change some settings on sony, eARC has to be set auto and digital audio out to auto 1, at first i thought digital audio out is only meant for spdif optical but it seems to have an effect on what the tv outputs using eARC/ARC. After changing these settings on sony and having my pre pro set to TV input, direct sound mode and rebooting both devices, i could get the truehd logo on my pre pro. However know that, from accounts of various people, eARC/ARC working successfully in your system has also got to do with your pre pro (or AV rec) brand or model, certain models have been reported to have problems. In case you aren't able to make it work and must play rips containing lossless audio from a USB drive, a workaround is using a 4k blu ray player daisy chained through the pre pro (or AV rec) to the tv, just connect the usb drive to the blu ray player's usb port, that will avoid any eARC/ARC sound problems.
