Hi

I am writing my audio driver for my board: TMPA910 CPU and WM8960 codec.
when I run pcm_min.c, there is an error: "Input/Output error".
I find that error because no DMA interrupt appear, printk() in DMA
interrupt program no appear

I have already set bit IE and ITC in DMA Configuaration register but no change.

Here is my source code.
Any idea, what could be the reason ?
