09-handling-channels-2.py - The `out` method and the physical outputs.

In a multichannel environment, we can carefully choose which stream
goes to which output channel. To achieve this, we use the `chnl` and
`inc` arguments of the out method.

chnl : Physical output assigned to the first audio stream of the object.
inc : Output channel increment value.
