Netflix 5.1 audio (English 5.1) is not working, occasionally gives a short burst of audio (less than a second) but always goes silent. Switching to regular audio soundtrack (English, or English - Audio Description) does work, sounds clear.
Sonos controller shows ' Unsupported' for audio in.
Recently updated to Sonos v8.1.1 - all Sonos devices and all controllers.
My kit is:
TV: Sony KD-55X8500E
Software version: PKG6.2508.0050PAA
I've also tried switching some of TV digital signal processing controls - no effect.
Disabled Sony TV ClearAudio+
DD output set to Dolby Digital - not DD+ Plus
refer attached images, mentions ARC & optical out muting.
I've had a troll through this forum - looks like there was something similar a couple of month ago on Sonos v7.x - attempted a couple of the user suggestion but no joy.

when this problem (no Netflix 5.1 audio) occured, i had relatively poor ADSL internet speed (about 3Mb/s download). I was getting by with using the Netflix Stereo audio (i.e. just 'English' not the 5.1).
A few days after logging this issue, my ADSL/Internet connection at home was upgraded and I now get about 11Mbit/sec download speed.
So I then tried selecting Netflix 5.1 audio selection -and it 'just works' again .... ? so i suspect there may be some magic Netflix network speed detection with throttling going on, perhaps ... ?
Regardless of how & why - my Netlfix is now working again via the Playbar and Play 1's I have for DD 5.1 surround sound
