Preich,
While I'm quite sure that the patch updates cures the audio acceleration issue, here's how to reduce the audio acceleration.
Windows button>Control Panel>Sound and Audio Devices, in the window that opens, click on the Audio Tab across the top, then on the Advanced button in the Sound Playback section. This brings up the Advanced Audio Properties window, Click on the Performance Tab and move the slider to the left to lower Audio Playback, hardware acceleration.
