Apps :: sound,opera and dsl

I added a directory of wav files and added these to opera..all files play in xmms and all but one play as test in opera..why does the one not play in test...also when running opera the sounds that play ( all but one) are very choppy..for lack of expression..why are the sounds choppy and can this
be solved...what plays the files for opera, xmms? is there a wave player that may solve for system sounds..can it be used to add system sounds to dsl...this is not needed just a possible customization but the opera sounds are of value for me . any thoughts appreciated..thanks

My guess is that this is a ram issue and I did get the ding.wav to sound when my download is complete and that is good enough for this machine
