alsa not playing the complete file - audio

Question

I am trying to read a wave file and play it on one of the sound cards on the board. Below is the code. I am facing several problems with this code.
I am trying to play files with various sample rates. With a file of Sampling rate of 8KHz, File doesn't play completely, even though the file dump shows entire content of the file.
If I play a file of 11025 Hz, I hear only noise
For stereo data I get garbled audio.
PS :
I am setting the rate obtained from the wave header
Period size is set to 10 ms. i.e for 16KHz - 160; 11025 - 110
ret = snd_pcm_open(&handlePCMHD, "hw:0,0",
SND_PCM_STREAM_PLAYBACK, 0);
if (ret < 0) {
snd_pcm_close(handlePCMHD);
return -1;
}
fd = open(fileName, O_RDONLY);
/* file dump */
fd2 = open("test.raw", O_WRONLY | O_CREAT);
if(fd < 0)
{
return -1;
}
/* Wave file header is 44 bytes */
if(read(fd, buf, 44)){
sampleRate = buf[12] | ((unsigned int)buf[13] << 16);
channels = buf[11];
}else{
//read failed
}
set_pcmhd_hw_param(handlePCMHD, sampleRate);
/* Buffer size = SampleRate * Number of Bytes per frame * No of Periods / For 10 ms */
readBytes = (sampleRate * 2 * 2)/100;
while((channels == 1) ? (x = read(fd, buf, readBytes)) : (x = read(fd, stereobuf, readBytes * 2)))
{
if(channels == 2){
StereoToMono_samples(buf ,stereobuf, readBytes/2);
}
write(fd2, buf, readBytes);
/* Number of frames = read bytes / 2 for 16 bit PCM */
x = readBytes / 2;
if ((ret = snd_pcm_writei(handlePCMHD, buf, (snd_pcm_uframes_t)x) == -EPIPE)) {
snd_pcm_prepare(handlePCMHD);
} else if (ret < 0) {
//error handling
} else{
count++;
}
}
close(fd);
close(fd2);
snd_pcm_close(handlePCMHD);
