This is achieved by holding three buffers in ctx->src_vbs[0,1,2] (f,f-1,f-2) This is achieved by using the ctx->sequence which gets reset via the s_fmt ioctl. These buffers are dequeued in stream OFF by calling free_vbs() But the corresponding references aren't removed anywhere. When application tries to stream ON and OFF continuously, s_fmt ioctl won't be called and it won't setup the srcdst parameters. Setting source/destination parameters in stream ON ioctl would make sure that the context is re-initialized before it is being used by the driver.
