I am facing problem related to DMA interrupt not getting triggered some times(out of 5 times one time it is happening) causing application to wait for the buffers(hw_ptr = 0) and no sound because of this.
I am using samsung soc with DMA controller PL080.I tried increasing periods_min to 4 but still no result.
I am using 2.6.29 kernel version.
