Chromecast + AC3 + Sony = no sound

So, I've tried a few solutions to similar issues people have been posting about, but no luck so far.

 

Short backstory: last week, my HTPC running a Kodi front end died. While waiting for parts for a new computer, I first tried passing movies and TV shows from my Emby server to my Sony Bravia KDL-48W605B over DLNA. The video worked fine, but there was no sound. Weird, I seem to recall it working before. Maybe that was my old TV set?

 

Trying to read logs and figuring out the DLNA settings didn't help, so, I tried with a Chromecast 2 instead. Same problem: video is running but no audio. More confusingly, some of the videos do play complete with sound.

 

A quick experiment (a log for which is attached) shows that:

 

* A MPEG4 video with MP3 audio plays fine, sound and all.

* Ditto for H264 video with AAC audio.

* H264 with AC3 (the majority of what I have), however, is mute.

 

It feels like there's a simple-ish solution I'm missing here, but what is it?

How is the chromecast hooked up? Is it connected directly to the TV or to an audio receiver?

The Chromecast is connected directly to the TV. The TV does feed the audio into an external amp over optical (as opposed to using its own speakers).

...and there we have it :) Forgot to set the digital out to PCM, so the amp was trying to output AC3, which it can't do. Thank you for the hint! I'll leave the thread as a reminder for folks who've missed the obvious, too.
