First, looking at the Phonon website they suggested I submit a wishlist to incorporate my audio hardware into the database.  Here's the output of the script from their webpage:
[Chris@localhost Download]$ sh soundcardinfo.sh

Second, I'm trying to use the program uniXM, which can be found on SourceForge, http://sourceforge.net/projects/unixm.  The program is supposed to allow me to connect to XM radio and listen to stations.  It requires QT 4.4 and Phonon.  I was able to get uniXM to compile and run but when I try to listen to a station I get this:
virtual bool Phonon::Gstreamer::AudioOutput::setOutputDevice(const Phonon::AudioOutputDevice&) "default"

Please let me know if there's any more information you need from me or anything I can do.
