Incidentally, there are only two pages that I know of on the web explaining how to use start-up flags in the command line (http://en.flossmanuals.net/pure-data/getting-started/starting/ and http://puredata.info/docs/faq/commandline).  None of them mention "-soundev". Is this a new flag ?
no, it's not new.

I always find it frustrating when i have to spend a lot of time figuring out how to use a command line program just because i don't know the syntax of the arguments.
pd -h give you all needed informations. you don't need a web access.
