[PD] pd~ set audio API on linux

[Christof Ressi]

Hi,

Can confirm on Windows. It's a spurious error message. I just opened a 
ticket: https://github.com/pure-data/pure-data/issues/1952

[pd~] is designed to pipe audio through the subprocess. The code does 
not (or rather should not) allow the subprocess to use a real audio 
device. Ideally, we should disable the "audio settings" and audio API 
entries in the "Media" menu for subprocesses, as they don't have any 
meaning in this context.

I highly doubt that this actually works.
