I just wanted to modify an existing driver Intel8x0 AC97 to do realtime playback of a sample. I'm still pursuing this. I have implemented a regular Linux userspace application for this at first and it provides a response latency smaller than 1 ms for 19 out of 20 triggers, but the 20th (on average) has latencies up to 20ms, which is totally unacceptable.
