Ok, please run the following test applet:Test Applet
Perform the following procedures and let me know the results:
1) Press "1" to run the OGG Stream Loop. Let me know if it loops or only plays once.
2) Press "2" to run the OGG Stream Sequence. Let this one play for a while, and let me know if it makes it through the sequence (you will know it made it through the sequence if it eventually plays the music loop from #1 above. Also let me know if the looping works or if the last music clip in the sequence only plays once.
3) Press "3" to run the WAV Stream Loop. Let me know if it plays, and if so if it loops or only plays once.
4) Press "Esc" and close the browser window.
This should give me a better idea where to focus the comments to locate the two problems you are having
NOTE: I don't think you mentioned what OS you are running. The above applet might not work on Linux (it won't detect the key events), so if that happens I'll have to come up with a different test. You might need to click on the applet's canvas for it to gain focus.
