> I keep testing the patchset, here's what I found so far:

Thanks a lot! This was really helpful. I've attached a patch which fixes a
couple issues mentioned below...

> 1. fixes at least bug #16513, bug #11628, bug #28748, bug #27749, bug #27603
> and a yet to be reported audio issue in Bloodrayne 2.

Great!

> 2. introduces audio issues in a number of games, these issues are ranging from
> - looping audio (Dark Fall, Atlantis 3)

Wasn't able to get Dark Fall running, and couldn't find a demo for Atlantis 3.

> - crackling sounds (Operation Flashpoint)

Tested Resistence, Cold War Crisis, and Dragon Rising and all seemed to work
fine. I ran into a "crackling sound" bug with the Critical Mass demo on Steam,
but that's actually an application bug that's made worse by this patch. I'm
still investigating that.

> - some sound effects are too loud, others are quiet (Max Payne 2)

This was caused by the volume patch. It seems to create more problems than it
solves, so I'm ditching it for now.

> - voice-over cuts out (Dracula: Origin)

Fixed in attached patch.

> - garbled, unrecognizable audio playback (Armored Fist 3, HoverAce)

Armored Fist 3 is a buggy app. The bad audio is caused by the same problem as
described in Bug 28945, Comment 4.

I couldn't get the HoverAce demo to run. It just loaded up some text viewer
with half of an HTML document in it.

> - performance degradation, severe audio stuttering (GTA: San Andreas, Star
> Wolves 3)

Couldn't find a GTA:SA demo, and SW3 demo died with StarForce DRM problems.

> Famitracker of bug#9358 stop working after applied your patch

Thanks for reporting. I think this is also fixed by the attached patch.
