Add the required nodes to enable SPDIF audio output on
the Beelink A1 set-top-box.

But the A1 doesn't have S/PDIF? Only HDMI plus a 3.5mm jack connected to the analog audio codec (and possibly the composite TV out) :/

Yeah, sorry - this patch wasn't supposed to be submitted upstream.

Regards,

Alex

Thanks,
Robin.
