Hi all, again

.
Here's my
mobo:
HP and Compaq Desktop PCs - Motherboard Specifications, PTGD1-LA (Puffer)
I got the X Cruiser case today, took me five hours to transfer everything over from the old case to the new, but i did it

, here's some info on the new case:
Aspire X-Cruiser Thermally Advantaged Case - Black
Everything was working fine, the three gauges on the front worked, i was happy. But after i rebooted my pc to test the reset button on the case, i noticed that the VU gauge/meter (measures dB/sound) was not working when i was playing music/games.
I have no idea what has caused this, i checked all the connections inside my pc, all perfectly fine. checked my bios, nothing there...so now i'm totoally clueless.
Appreciate any replies. thank you!.
