In fact, in that revision you're using still uses the old audio engine that is buggy like a hell. It may not be the case for Sonic Adventure 2 but in many other games it causes issues like missing effects, background music cutting out, cracks/clicks and so on. Since you decided to use an old build, you won't get support, so you will have to deal with bugs like the ones you mentioned (none of them occur in 4.0 stable and current development builds)...
