Most audio examples have a command-line option to specify the audio device.
For output scripts, this is -O, when coming from a mic input, it's -I.
Instead of specifying it in the config file, you could just put these on
the command line. But it's probably better to have it permanently put into
the config file so you don't have to keep typing it in all the time.

Thanks for the replies everyone! Tom, I'm not entirely sure how to "pass \
"-O<br> pulse"", but I did change gr-audio.conf to use pulse and that \
