I experienced this problem (although for me the sound come back as soon as I stop the java applet, sometime I had to stop firefox too, but I never had to kill the X server).

An intersting workaround, for people awaiting this bug to be fixed : I you start a program using sound (eg. Totem) BEFORE starting your java applet, then you will be able to hear the sound of your program (note, you well not hear the sound of the java applet, depends wich one you prefer).

I had/have a similar problem as well, although in my case, like Thomas Detoux's, killing java gave me sound back. I was able to "fix" it by using the ALSA wrapper for OSS applications (package alsa-oss, command is aoss) before launching java. I was losing sound even when the java program I was running did not use sound, although not right away.

I didn't try it with applets, but it make work if you do the same to firefox.

Thank you for taking the time to report this bug and helping to make Ubuntu better. I noticed the package your bugging is updated in Karmic. Does this occur in it? Thanks in advance!
