I assume you're talking about the SDL 1.2 core audio API.
You provide a stream of samples. Once you have provided the samples
they are played. It's one-way; you can't magically get back the audio
from seven seconds ago out of the sound card. If you need to seek
forward and backward in a preëxisting waveform then you have to do it
separately, which can include implementing it yourself or using other
libraries such as SDL_mixer that are designed for more abstract audio
