Only these settings are AM62D specific here:
* api.alsa.path
* audio.channels and position (could be modified as needed)
Others could be left to default (most are redundant as they point to
default values and only added for reference) PipeWire: Index
<https://docs.pipewire.org/page_config_xref.html>
I will experiment with other parameters later to see if they result in
any performance improvement.
Primary goal was to add 8-channel configuration for AM62D codec
otherwise AM62D also works with the default stereo config.
Same case for other platforms they can use default stereo config or
follow AM62D config for multichannel (depending on board codec)
