Running audioconvert in merge+split mode is the only way to make this work with the adapter, since the adapter does not support passing multiple channels on a single port right now, and if it does at some point, it will be without a mixing node on the port, which means we will not be able to mix multiple audioconvert nodes on the same adapter. In the future we need to consider writing a lighter volume node with multiple channels support to replace audioconvert. The new linking algorithm now takes into account the channel positions and makes sure to link the correct channels together. Also, it avoids passing the port proxies inside the GVariants, thus making the algorithm a bit more generic and easier to unit test.
