While this game may experience problems on your dedicated sound card, you should be able to use your integrated device instead. You should temporarily disable all Sound Blaster devices and set your integrated device as the default audio playback device. You should also plug your headphones/speakers to that device for the duration of playing the game.
To do this, go to your Control Panel -> Sound, find the Sound Blaster sound device(s), right-click and select Disable (for each one, if there are many). Afterwards, find your integrated playback device (typically, that would be a Realtek card), right-click it and make sure it's the default device. Once all changes are made, click OK and try playing the game.
You should re-enable the Sound Blaster device(s) and set the playback device to the default once you no longer need to use the integrated device.
