Hi,

The audio subsystem in platform has its own buffering. It could buffer upto 256KB. Our driver uses indirect callback to send the buffers and sizes to audio subsystem whenever the "ack" is called. If rewind is required during the playback, ALSA pcm native interface is not calling the driver operations for rewind.

I am planning to add rewind operations to pcm_ops and make changes to pcm files. Please suggest me whether this is acceptable.

Thanks -Sing
