AU9000 owners help with DD sound

Dear all,

I have an AU9000 50" TV which I've had since summer last year. It is connected to my AVR171 amp through HDMI arc and has worked without any issue until now...

On using them both recently I've noticed I am no longer getting Dolby Digital to the amp and there is no longer an option for Bitstream on the TV audio settings (just PCM or AUTO with passthrough greyed out). Dolby digital works on other HDMI input devices such as a Chromecast on the amp, and through optical from the TV to the amp but this means I can't then use the one remote. I've reset the TV which hasn't helped and Samsung aren't being overly helpful.

I don't have any other ARC devices to test the HDMI arc output of the TV so wondered if any others had come across this problem? The firmware was automatically updated in Feb 2022 to 1904.0 which I think might be the issue as it worked before this, although I can't remember exactly how long. There is no way get the old firmware back as I can see.

Any help would be much appreciated!

Thanks,
Simon
