AAC | ADPCM | Convolution | DAFx | FFT | IIR | Mixer | MP3 | MPEG | MPEG-4

Hi all
I am working on playing a AAC  decoded file on the speaker side on a
ADSP board.
To begin with , I have simply take a PCM buffer and am trying to play it
on the speaker.
I am using ping -pong buffer implementation wherein I am first writing
data to buffer. Then through DMA , I am transferring this data to DAC
which is connected to speaker. While this buffer is being played on
speaker , I am filling another buffer simultaneously . Once the first
buffer has finished playing, I play from the second buffer and
simultaneously fill the first buffer , and so on.
The problem with above implementation is that along with the actual
sound, there is a click-click sound as well.
If I do not use ping -pong buffers and rather play the big buffer in
single go, then sound is absolutely clear.
I  was using  buffers of 2K initially but I tried increasing there
sizes. Nothing is improving the quality.
Kindly let me know if anyone comes up with a different implementation.
Regards
Sanjam
