RTOS/CC3200MOD: TIDrivers CC3200 I2S, issue playing sound from FS

Tool/software: TI-RTOS

Hello,
 We are having issues with I2S on the CC3200. We are trying to play a sound file(16-bit, stereo, 16Khz sampling) from the SimpleLink file system. The file seems to read in fine from the filesystem, but no sound comes out of the TLV320AIC3254 DAC and we encounter a DMAERR interrupt after finishing. We have had it working prior when doing testing with out the TIDriver library. I know the DAC is setting up correctly as we are using the same register configuration and code from our original test bed(using I2C_Open, I2C_transfer, etc). I attached the code below

unsigned short fileBuffer[30*1024];
_u8            tBuffer[3072];

int playSound(char * fileName)
{
	int 			offset= 0;
    long            DeviceFileHandle;
    long            lRetVal = -1;        //negative retval is an error
    SlFsFileInfo_t  pFsFileInfo;
	I2S_BufDesc     bufDesc[3];
	I2S_BufDesc    *pDesc = NULL;
    char fil[] =    "ding.wav";

	Semaphore_pend(slSemaphore, BIOS_WAIT_FOREVER); // Wait for NWP to access FS
	Semaphore_pend(semWaterMarkHandle, BIOS_WAIT_FOREVER); // Wait until I2S handle is opened

	System_printf("SOUND: Playing sound\n");

	// Open File
	lRetVal = sl_FsOpen((unsigned char *)&fil, FS_MODE_OPEN_READ, NULL, &DeviceFileHandle);
	if(lRetVal < 0)
	{
		CloseSoundFile(DeviceFileHandle);
		//System_printf("SOUND: Failed to read file %s\n", fileName);
		return -1;
	}
	// Read from file and discard wav header
	// get info on the file
	lRetVal = sl_FsGetInfo((unsigned char *)&fil, NULL, &pFsFileInfo);
	if(lRetVal < 0)
	{
		CloseSoundFile(DeviceFileHandle);
		//System_printf("SOUND: Failed to read file %s\n", fileName);
		return -1;
	}
	// Read from file
	lRetVal = sl_FsRead(DeviceFileHandle, 0, tBuffer, 4);
	if(lRetVal < 0)
	{
		CloseSoundFile(DeviceFileHandle);
		//System_printf("SOUND: Failed to read file %s\n", fileName);
		return -1;
	}
	// discard wav header
	// read header
	// check if file is a wav file
	if ( ( tBuffer[0] != 'R'
		  || tBuffer[1] != 'I'
		  || tBuffer[2] != 'F'
		  || tBuffer[3] != 'F' ))
	{
		System_printf("ERROR: Not wav format\n");
		CloseSoundFile(DeviceFileHandle);
		System_printf("SOUND: Failed to read file %s\n", fileName);
		return -1;
	}
	System_printf("SOUND: Sound is RIFF Wave\n");

	offset += sizeof(waveHeaderType);

	_u8 *ptr = fileBuffer;

	bufDesc[0].bufPtr = ptr;
	bufDesc[0].bufSize = 3072;

	ptr += 1536;
	bufDesc[1].bufPtr = ptr;
	bufDesc[1].bufSize = 3072;

	ptr += 1536;
	bufDesc[2].bufPtr = ptr;
	bufDesc[2].bufSize = 3072;

	ptr = fileBuffer;
	System_printf("ptr: %x\n", ptr);

	sl_FsRead(DeviceFileHandle, offset, tBuffer, 3072);
	memcpy(bufDesc[0].bufPtr, tBuffer, 3072);
	sl_FsRead(DeviceFileHandle, offset, tBuffer, 3072);
	memcpy(bufDesc[1].bufPtr, tBuffer, 3072);
	sl_FsRead(DeviceFileHandle, offset, tBuffer, 3072);
	memcpy(bufDesc[2].bufPtr, tBuffer, 3072);

    I2S_writeIssue(i2sHandle, &bufDesc[0]);
	I2S_writeIssue(i2sHandle, &bufDesc[1]);
	I2S_writeIssue(i2sHandle, &bufDesc[2]);

	int doneReading = 0;
	int i = 2;
	while (!doneReading) {
		i++;
		ptr += 1536;
		if(i==10) {
			ptr = fileBuffer;
			i = 0;

		I2S_writeReclaim(i2sHandle, &pDesc);

			while (1);
		lRetVal = sl_FsRead(DeviceFileHandle, offset, tBuffer, 3072);
		if (lRetVal < 0)

		else if (lRetVal < 3072)
		{
			doneReading = 1;
		}
		//System_printf("ptr: %x\n", ptr);
		memcpy(ptr, tBuffer, lRetVal);

		pDesc->bufPtr = ptr;
		pDesc->bufSize = lRetVal<3072?lRetVal: 3072;
		I2S_writeIssue(i2sHandle, pDesc);
		offset+=lRetVal;
	}

	System_printf("SOUND: Done playing sound.\n");
	CloseSoundFile(DeviceFileHandle);
