dsound-related crash backtrace

I'm testing with SNES9x 1.53, Wine 1.5.18, Lubuntu 11.10 x86-64, Nvidia driver
304.64.

I get a crash on changing the sound driver setting. To reproduce:
- Download and unzip the snes9x archive.
- Run snes9x.exe. You'll get a dialog saying "Unable to initialize XAudio2"
since Wine doesn't support that. Click OK.
- Select Sound->Settings..., change Sound Driver to Snes9x DirectSound and
click OK. The program crashes. Since it saved the DirectSound setting to
snes9x.conf, you get an immediate crash if you run snes9x.exe again without
deleting or editing snes9x.conf.

The crash seems to be related to the sample rate. The default playback rate is
32 KHz. For me, if I change Sound Driver to DirectSound and Playback Rate to 48
KHz, there is no crash. I can load a SNES ROM and play it with (albeit crackly)
sound. The crash happens when selecting any other playback rate.

(There is no graphical output in the default Direct3D mode which I'll hopefully
file another bug for. You can select Video->Display Configuration... and change
Output Method to DirectDraw to work around that.)

This looks like a regression. A regression test gave this:
