This shouldn't be an issue anybody has. We've had Dolby surround sound for over 40 years now, and everything was fine until recently. We had quadrophonic sound years before that.

Well it's still their fault for not making sure their audio works on a normal, non-surround setup

Also worth noting that we switched the audio track to Spanish and you can hear it just fine.

Probably because the Spanish track isn't delivered in surround...

That's not what the link says. In fact it is specifically saying it should be working in stereo but tdolby surround has missing channels.
