Hi,
I'm trying to watch disney+ on my Bravia A1 in India. This is hooked up by an optical cable to a Yamaha YSP-3000 soundbar. The splash screen for the programmes show a Dolby 5.1 logo - and the audio options displays two choices, a 5.1 and 2.0. Even with the 5.1 option selected by default, the soundbar receives only a 2.0 PCM output. I've tried changing various settings on the TV but nothing seems to help. Other apps like Netflix, Prime video, and my PS4 all output surround. I'd be grateful for some guidance. Here's some information on software/app versions and such.
Many thanks in advance.
