Hoping someone may be able to help. I have an issue where when using any Android TV apps (such as Kodi), my TV (KD-65XE9005) gets stuck sending a specific type of audio signal (eg PCM) to my Denon amp (AVR-X2400H). The TV and AMP are connected via a single HDMI, and using ARC.

For instance, if I turn everything on from afresh, the TV sends a 2.0 stereo signal to my Denon amp whilst browsing the interface and selecting an app. Sat I choose to open Kodi, Kodi opens and again everything as normal - 2.0 stereo signal.

Then I try to play a video with a 5.1 audio track - the TV sends PCM via ARC and the amp updates to show Surround/PCM.

However if I then close out and open another video file with a 2.0 stereo sound track, the TV continues to send PCM to the AMP (or at least the amp continues to show Surround/PCM). I can hear the stereo track despite the AMP showing Surround/PCM still.

This works both ways and is more of an issue the other way around - TV appears to push out stereo despite my playing a 5.1 movie, all because I have previously watched something in 2.0.

In terms of my set up:

• TV is connected to AMP via HDMI/ARC
• Android TV is 7.0 and it tells me there are no FW updates from Sony
• Android TV settings as follows: ** Speakers = Audio System ** Sound Mode Sync = On ** A/V Sync = Auto
• Kodi Settings as follows: ** Number of Channels = 5.1 ** Output configuration = Fixed ** Allow Passthrough = On

Basically, tl;dr I can’t work out if Android is sending my amp the wrong signal (it gets stuck on the first one), or if my amp is getting stuck/not updating the display and actually things working normally!

Please help!!
