Splitting RCA audio from HDMI

[Output Flange]

I need to replace my old AppleTV with a new model.

My current AppleTV has the HDMI output going into my HD matrix, plus the optical output goes into a converter which then connects via RCA to my multiroom audio amp.

The new AppleTV doesn't have an optical output, only HDMI.

So, I need a recommendation please for a splitter to turn the HDMI output from the AppleTV into HDMI output plus RCA.

As always, there are a bunch on Amazon starting at £20, but I'd rather go for something that's tried and tested.

Thanks!

Thanks all.

I've ordered a CYP de-embedder, should arrive in the next couple of days.

I'm not fussed about 4k (I don't own anything 4k) so that hasn't influenced the choice.

Interesting point on using the Airport Express - hadn't thought of that! Ah well.
