I don't know about your soundcard, but many (cheap) soundcards only
support 48kHz. You probably won't notice it with ALSA, since ALSA is
capable of resampling the sound before pushing it to the card, but if
you really are using old-school OSS, I think  there is no way to

Just in case, you're sound card really only supports 48kHz, would
resampling your audio files be an option? At least then you have some
control over the resampling quality.
