On our system, using mplayer to play a movie that has 44.1KHz audio (hardware only supports 48KHz) can cause audio stuttering if we're using OSS emulation, but not if we're using native ALSA. Is this a known problem? Does OSS emulation hog the CPU?

It won't as long as you do right :)

Mostly this kind of problem is the difference of parameters. Try to reproduce the playback with the same parameters used by OSS emulation (you can see /proc/asound/card0/pcm*/sub*/hw_params) with ALSA API.
