But, CONFIG_SND_MULTICHAN_SUPPORT would change any buffer allocation behavior? I don't find it...
It will change the ac97 frame size defined in bf5xx-ac97.h,the frame size the basic unit of the DMA buffer
So this is purely a restriction in the driver, rather than a property of the hardware - is there any reason why you can't change the size of buffer that you allocate at runtime?
