Some sound files in Ubuntu gives cracked sound, but the same files run on Windows without any problem! Why it is happening? Moreover, when I record screen captures and record sound using a microphone, I hear crusty sound in reply. But same speaker works smoothly in Windows.... How do I solve this?

I am using Ubuntu 14.04 LTS.

Edit: Sound card info...

Open sudo nano /etc/modprobe.d/alsa-base.conf and add options snd-hda-intel model=MODEL to it, changing MODEL to the model name such as acer.

It would also be helpful to know what computer you are using.
