How to get 5.1 surround audio to external audio amplifier from Sky streaming puck

[KaiTa]

I have old Sony KDL-46W2000 TV and Sony DAV-DZ810W HTS (home theatre system). I can connect digital audio from Virgin Media box to HTS with optical audio cable. Recently I switched to Sky streaming puck. Unfortunately the puck doesn't have optical audio output. Would someone please advise me how to get 5.1 audio streams to the HTS? The TV has only stereo output, the HTS can receive digital audio via coaxial cable in addition.

@KaiTa unfortunately the old Toslink optical connections are frequently missing on newer equipment as HDMI  ARC has become the default audio output. However you can buy a HDMI audio extracter (like this example) which has the necessary Toslink output.

Whatever you buy must have an external power supply - some cheap units use power from the HDMI output which doesnt work with Sky pucks - and support HDCP2.2 if using UHD.

I wonder if I can ask Sky provides an eARC box. It seems SkyQ had the accessoriy in package.

Sky will not provide you with additional hardware to allow you to connect your external amplifier. 

Sky Q is now nearly 10 years old. Q's optical output was just the most common audio technology of the time.

HDMI ARC/eARC has now superceded this on most home audio/visual setups.

The Sky Stream puck is a more modern, smaller device, mass-produced for the mass-market around the world. The addition of an optical digital output would have added significant amounts to manufacture costs, but for a continuously reducing number of customers for whom it might be useful.
