I just bought X9S and overall I'm happy with it! I just have one issue with playing AAC 5.1 tracks, apparently they all play as stereo

You have to select "Auto" under Realtek Audio settings. http://forum.kodi.tv/showthread.php?tid=...pid2425640

Thanks for quick response, unfortunately I should mention that I'm using Optical output, due to lack of 4k support of my 4 year old AV Denon Receiver (only HDMI 1.4b). So HDMI goes directly to TV (2.0 -> 2.0), and optical output to receiver but S/PDIF output setting in audio options has only RAW or PCM 2 channel to select not auto
Is there some other setting so that AAC will work through optical output?

Thanks again
