Crash on high-cpu-load and SoundMAX

[kbe]

Hi. I have asio4all 2.6 on SoundMAX (ASUS A7V8X-X integrated card - latency 1.333ms on 48kHz, buffer=64, kernel buffers=2, cpu-atlon xp 2000+). On high cpu load, computer crash - reset or error like
DRIVER_IRQL_NOT_LESS_OR_EQUAL etc . With directx driver works ok.

This sounds like a bug in the smwdm.sys miniport. Does the problem persist if you up the buffer size to - say - 256 samples? A latency of 256 samples is still inaudible with a WavePCI miniport. DirectX works with larger buffers anyway. Alternatively, you could try to switch on hardware buffering, which also lowers the h/w interrupt frequency considerably.
