First of all, thank you for all the great work. All of us who want to have audio passthrough, so our highly paid HiFi equipment is put to work, are having problems finding devices that actually do that. After so many headache with Plex and different versions of OSs (basically, only bulletproof solution was HTPC with Windows or Linux, which adds to cost) I've finally stumbled on your solutions.
I have Yamaha RX-V4A with 5.1 setup, which is connected to Philips TV. The box is Tanix TX6. Kodi reports in HDMI connection that it is connected to Philips TV HDMI, not to AVR (AVR supports Video passthrough). DTS, DD, DDP, DTS-HD MA, TrueHD work. With TrueHD I have problems that sometimes the audio cuts off, AVR reports that there is no decoder, then it comes back. That happened to me with high bitrate movies. I yet need to test with lower quality rips.
Thank you and highly appreciated.
