If you are using an Oppo 203 to feed the TV the 4K signal, you can use the secondary audio only output to the HD621.

Higher end equipment tends to have dual HDMI outputs.

More consumer level devices, XBox/PS5/AppleTV 4K etc will need a Vertex2 or the newer VRRoom since they only have a single HDMI output.
