[wdmaudiodev] Optimal KS buffer sizes ?

A user is complaining that our KS audio system has around 70ms latency (RealTek AC97 chipset). The app has 2 buffers of between 384 and 512 samples. The audio quality is good (no glitching) - so this figure seems hard to believe unless more buffering is taking place further down the stack. Is there any way to query the device for buffer sizes etc ? What is KSSTREAMALLOCATOR_STATUS all about and can it help here ?

Thx

Jerry
