I doubt the noise is due to alsamixer. While the pipeline is playing, I tried
all permutation combination of gains on the mixer. The noise did exist

The card is Intel's onboard linein - Intel PCH. This is what arecord -l
shows
**** List of CAPTURE Hardware Devices ****
card 1: PCH [HDA Intel PCH], device 0: ALC892 Analog [ALC892 Analog]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 1: PCH [HDA Intel PCH], device 2: ALC892 Alt Analog [ALC892 Alt Analog]
  Subdevices: 1/1
  Subdevice #0: subdevice #0


Certainly can not be a hardware issue since its works like a charm on
Windows :/
