Probably something with how the drivers interface with the card.
Vista is more locked down, im not a programmer so i dont want to talk out my ass, but it seems like alot of companies seem to be haveing vista driver problems.
Frankly, creative is the biggest aftermark soudncard producer, and historically (at least since t he sb16 okay okay, the 64 awe and the 128 were OK, but i think i had some problem swith the 128, but that coulda been because of 98) their drivers SUCK TOTAL ASS.
Ive never had more problems than i have had with creative products.

It's the new Vista audio subsystem that was re-written from XP with a new interface for the drivers. They changed it to move the software from kernel to user space to get rid of audio system triggered BSODs, support new DRM technology, etc. That means that if you are playing a game or using an application that was written with DirectSound you will get absolutely no hardware sound acceleration at all under Vista, no matter how fancy your sound card. That's why many game engines have switched over to OpenAL for audio, because OpenAL bypasses the Vista kernel's kMixer and can talk directly to the vendor's HAL.

Your specific example of output is probably due to this (from the first link):
| Quote : | | "Second, with the way this new emulation structure, all “MME” and “Direct Sound” applications will ultimately result in pre-mixed PCM audio that is sent to the driver in one and only one format (in terms of sample rate, bit depth and channel count), and that format is governed by a control panel setting that Microsoft would prefer be configured only by the end user. This eliminates any opportunity for hardware to accelerate sample rate conversion or to take full advantage of advanced SRC technologies..." |
