AAC sound 5.1 on my DVDplayer correct?

Is there any way to test the audio channels, to be sure my dvd player works correct? (5.1 with AAC sound)??
----
I have my PC connected to DVD player (spdif), so i was just wondering if there is any test file (AAC), so i can hear each channel, if it works right. When I watch movies with AC3 sound, it works, I'm just not sure about AAC sound.
Thanks

nobody know where i can get some file to test it?
