SIO_ready function never get true

I use:
Bios_5_42_01_09.
Ccsv6.
Edma3_lld_01_11_03_01.
Pspdrivers_01_30_00_05.
Xdctools_3_30_03_47_core.

Problem in string number 99.

I can get data from codec. I forever wait SIO_ready. It is not work when i use 2 or more buffers. When buffer is one it is all works.

I not use aic31 driver and audio driver, only mcasp.

Part of my code:

#define BUFLEN                  4096
#define BUFALIGN                128
#define NUM_BUFS                2

Uint8 buf[NUM_BUFS][BUFLEN];
extern Int edma3init();
extern EDMA3_DRV_Handle hEdma;
extern Mcasp_ChanParams mcasp_chanparam;

        /* .rmask    = */ 0xFFFFFFFF, /* All the data bits are to be used     */
