Locate / Replace Incredible Volume Rocker Sound?
 

I have had good experiences with PPCG in the past, so I have come back to you needing help...

Can someone tell me where to locate the sound file used when you press the volume rocker on the Incredible? It is a small "doot" sound. I want to manipulate it, but cannot locate it. Perhaps a ROM cook can help me out? Thanks in advance!
