The Orange Pi Zero Plus 2 has the same pinout[1] as the Orange Pi
Zero[2] (with the possible exception of line-out left/right being
swapped), and the Orange Pi Zero Interface Board is sold[3] as
compatible with both of them. We can thus use the same audio routing.

The subject is misleading. The Orange Pi Zero2 is a different board with
the H616 SoC.

Oh, indeed. I got confused. Thank you for catching this error!

The Orange Pi Zero interface board is a (mostly) passive adapter from the
13-pin header of the Orange Pi Zero and Orange Pi Zero Plus2 to standard
connectors (2x USB A, 1x Audio/Video output, 1x built-in microphone, 1x
infrared input). Headphones, microphone, infrared (CIR) input, and USB
have been tested with the Orange Pi Zero.
CVBS output is currently not supported.

The Orange Pi Zero interface board is a (mostly) passive adapter from the
13-pin header of the Orange Pi Zero and Orange Pi Zero Plus2 to standard
connectors (2x USB A, 1x Audio/Video output, 1x built-in microphone, 1x
infrared input). Headphones, microphone, infrared (CIR) input, and USB
have been tested with the Orange Pi Zero.
CVBS output is currently not supported.
