First of all, I wanted to thank you for your work on this. Though I don't mind most of the Brawl voices, there are some (Fox, Peach, Mario) that I can't stand, and a couple more (Gdawg and Link) that I simply like the Melee versions of better.
For 3.0, so far I've only tested your Fox, and almost everything works perfectly. But I did notice that for his first jump, roll dodge, and when he's leaning over a ledge, it's completely silent for me. In your video, Fox clearly has the "ah-tah" for leaning over the edge, but I couldn't tell for the other two if there was a sound. I'm using Riivolution (1.4), and I only inserted your latest Fox pack (17.sawnd). I of course put the FitFox.pac in as well. I didn't insert the MeleeSFXPack.sawnd (wasn't really clear on what that changed), so could that be the issue?
