Assuming the format is the same format used in /etc/asound.conf, what you
need is known as a "parser" and you need one which can be invoked from bash.

There is a project for writing configuration file parsers


but it does not seem to include one for .asoundrc. A quick Google search
turned up nothing. The functionality you need is probably available through
the Alsa library, but I suspect this would require some C programming.

You might find more helpful advice in the pages of the Alsa project


including where to ask the above question again.

There is no place like /home.
