Even though the situation described is strange to the point of having never happened in history you would still need to ask an admin to write policy to implement your interesting audio permission scheme just the same as one would need to ask an admin to add a group or you know automate the process with a gui or integrate the change in groups into updating or software installation.

I am sure that somewhere having an actual programming language available vs list of what can and can't be run with or without a password would enable some additional power in terms of control of the system but I cannot for the life of me imagine a situation where it would be all that useful.
