Asus Zenbook ux32vd mic static noise

The problem is in static noise with and without PulseAudio

I recorded (arecord -d 5 test-mic.wav) it and put it here

$ lspci | grep -i audio
00:1b.0 Audio device: Intel Corporation 7 Series/C210 Series Chipset Family High Definition Audio Controller (rev 04)

$ arecord --list-devices
**** List of CAPTURE Hardware Devices ****
card 0: PCH [HDA Intel PCH], device 0: ALC269VB Analog [ALC269VB Analog]
  Subdevices: 1/1
  Subdevice #0: subdevice #0

It works well in Windows 8 but not in Linux (I tried different LiveCDs - all the same)

I tried to apply this guidance but id didn't help.

$ arecord -f dat -r 60000 -D hw:0,0 -d 5 test.wav
Recording WAVE 'test.wav' : Signed 16 bit Little Endian, Rate 60000 Hz, Stereo
Warning: rate is not accurate (requested = 60000Hz, got = 48000Hz)
         please, try the plug plugin 

$  echo autospawn = no >> ~/.pulse/client.conf
$ pulseaudio -k
$ LANG=C timeout --foreground -k 10 -s kill 10 pulseaudio -vvvv 2>&1 | grep device.buffering -B 10

$ cat /etc/pulse/daemon.conf 
....
default-fragment-size-msec = 6
default-fragments = 4

default-sample-format = s16le
default-sample-rate = 48000
default-sample-channels = 2

After all of that is test2.wav which is also very noisy.

$ arecord -f dat -D hw:0,0 -d 5 test2.wav
Recording WAVE 'test2.wav' : Signed 16 bit Little Endian, Rate 48000 Hz, Stereo
