Windows In previous Windows releases, the entire audio stack ran in Kernel space. Vista will put an end to this. "The first (and biggest) change we made was to move the entire audio stack out of the kernel and into user mode. Pre-Vista, the audio stack lived in a bunch of different kernel mode device drivers, including sysaudio.sys, kmixer.sys, wdmaud.sys, redbook.sys, etc. In Vista and beyond, the only kernel mode drivers for audio are the actual audio drivers (and portcls.sys, the high level audio port driver)."

Well, as long as you use them sparingly, then you shouldn't have a problem; I don't think the contextual switch would be unnecessarily high if video, audio and possibly the network stack was kicked out of kernel space.
