Some Music Won't Play

[scsever]

I have an 8.10 hybrid.  I've moved my audio files from another linux machine to the hybrid via SMB and put them in the public audio directory, I then did a synch via the web admin (have actually tried this a few times).  When I select to play them some will play and some won't.  Below is what I have tried to remidy the problem but unsucessfull. 
Tried playing by atrist, album and individual song: some will play and some will not.
There is a mix of ogg and mp3: verified that some of each type will play and some of each will not play.
Checked naming convention: some have underscore with no spaces, some have spaces, some have punctuation with spaces and punctuation with underscore and no spaces but nothing is consistent when comparing what will play and what won't.
Checked permissions: scsever(me):public is set on all and scsever:public have rwx
Tried playing via Amarok in the KDE desktop on hybrid: get an error that there is no audio device, however in Linuxmce some music will play and all videos have no audio problems.
Moved entire content of audio directory to another linux machine and all music plays via Amarok.

I have no idea what else I can do.
Any ideas what could be the problem?

Thanks,

disclaimer:  A number if the things that work for me may actually work by coincidence and not actually be a global solution.

That said I recently had the same issue.   What happened for me wad that I moved my media from a parent folder to a child-   I really just put each artist in a folder organized by the first letter of the artist.   At any rate, afterwards the update media didn't change the location of the files in the database.  Don't know why although I'm not using the lmce directory structure. I had to do a media sync and purge the database and just wait until the update daemon rediscovered the media.

I have not had a problem since.  Using a dns-323
