Adobe Acroread and Sound files in PDF's

I work for a school district, and we are trying to push OpenSUSE as best we can! One thing that is holding us back is we have a subscription to www.pearsonsuccessnet.com, which allwos us to read ebooks in PDF format. These books contain sound files which play fine in Adobe Acrobat Reader for windows, but require another media player in SUSE. I have done the “Restricted Formats for OpenSUSE 11.2” instructions and DVDs play and flash videos seem to work fine in Firefox. Any idea how I can get this rolling? It might mean a Linux mobile lab if I can make this work!
