Issues Related to 8.0 Oreo Update
Some users have reported issues related to sound once their Android operating system is updated to 8.0 Oreo
If you connect Sony Home Theater system (Soundbar, A/V Receiver, etc.) to output the sound from your Android Smart Television, Android™ 8.0 Oreo™ update (v6.5830) may result in sound related problem where you will not hear sound through your Home Theater system if the Television remains on standby for too long. Please be aware that only a handful of Sony Bravia TV users have reported this after their TV set was updated.
Android have tried to resolve this by a new version (v6.5850) of the Android™ 8.0 Oreo™ update which should fix this sound related issue.
Sony Bravia provided the automatic update for Android 8.0 Oreo resumed in April 2019 on a staggered schedule ( you can obviously chose to postpone the download / update) so it may take some time before this new version it is sent to your Bravia Smart TV. You can always download the update at your convenience ( if you are too keen) from your Android TV model support page and follow the instructions to manually install it (would require a external drive / USB flash memory drive).
However, like in most cases you can wait for the automatic update, you can follow the options below to temporarily address the sound issue.
Follow the workarounds provided in order. If the symptom(s) persists, use the next workaround.
Please be aware that you need to set the Audio system prioritization to On before you begin.
