Make a new method to parse parts of the audioinfo based on custom keys, leaving unparsed values to defaults. Implement the generic audio parsing with this. We can then remove some duplicate code where the audio keys didn't match or where only parts of the info needed to be parsed. Also make a method to serialize the audioinfo to properties and use that when making arguments to load the modules. Avoid doing some custom property serialization, move all key/values into properties and serialize those with the generic functions.
