We picked up a Panasonic Freeview box but discovered it only has digital coaxial sound output. Our sound system is circa 2012 and has RCA and optical sound input only.

 

Is there a cheap way to get the coax out to RCA? Anyone have any recommendations? Investing in a whole new sound system seems overkill. I've seen some cheap converter boxes on Trademe but I wonder if they work well esp. for surround sound?

Fair to assume the OP means left/right line level audio when they say RCA.

There are lots of cheap coax to optical audio adapters around - try jaycar

Meant to add - coax audio to optical should keep it digital and preserve surround sound

I bought a box like this one https://www.aliexpress.com/item/33052702646.html from jaycar ages ago, but it was grey and way more expenive. Worked fine. They dont seem to sell it anymore.

 

Used it because coax from the garage veon TV to the amp would always drop out with powertools switching on and off etc and also having it there made the HDMI into the TV freak out in those same power transients. Going optical there broke the ground loop and happiness was restored mostly except for the fire TV box which had the most dropout prone HDMI output I have ever had. Still 90% better tho.

 

 

 

The signal is the same between the 2 formats, you could possibly get an optical tranmitter off an old motherboard or dvd player or other obsolete equipment and hook it up to the coax out and a 5v supply if the pretty box version is too hard to find.

Of course. I immediately thought SPDIF over RCA coax.
