I have something similar on an ACER Aspire 3618, 1.8GHz Pentium M 735A, 2 GB RAM Laptop. I've recently installed Intrepid Ibex (8.10) Alpha 6 on this machine and when going to Notifications and setting them for KDE Windows Manager on Maximize, Minimize, the normal "windows sounds", these are the default sounds I'm using, No sound is heard when doing those functions to a Window. If you get real close to the speaker you can here a click sound as if it was trying to play. I did as above with no change. I really don't know if this is the same as here, but it really sounds very similar. I'm attaching my old file and new file as done above.
