Got a beater Walkman/CD/mp3 player? Got an isolation transformer to power the radio and some lousy AC powered audio source with a line out jack? Got an audio signal generator? Audio is audio.
There is a small chance you could fry any source device by touching it to high voltage...use something you don't care about or a test generator designed to take some abuse, or be extra careful in how you go about connecting it (dc blocking caps are not a bad idea).
