I also wanted to do that but likewise received static.
For future reference, use whatever means you need to grab the hca files from the Sounds folder. Exctract them from the acb archives; I used VGMToolbox.
After you do that, you can play and even convert the raw hca's with Foobar using a plugin (found here: http://www.foobar2000.org/components/view/foo_input_vgmstream)
Worked for me.
