<http://www.alsa-project.org/db/?f=9871b38d99bdd4cc91e398b60eb31361eb305395>the
issue :

when i record with mic i get always a bad recording with some tic tic tic
tic , does not matter if i use low volume for the mic i can hear them
anyway...

if i use louder volume i can hear them ...

i tried with

arecord --quiet --file-type wav --rate=44100 -D plughw:Intel  test.wav

with this there is less rumors

when i play with

arecord --quiet --file-type wav --rate=44100  test.wav

i got a lots of problems ... alsa (snd_pcm_recover) underrun occurred

the strange thing is that on kubuntu 8.04 it was workin better ...  that was
my screenshot of alsamixer in the terminal

fixed

my cards eats only 48000  with this

ffmpeg -f  alsa  -ac 2 -ar 48000  -i hw:0,0   -s 1024x768 -f x11grab -r 30
 -i :0.0 -acodec pcm_s16le -vcodec libx264 -vpre lossless_ultrafast -threads
0 output.

works note ar 48000

with this

ffmpeg -f  alsa  -ac 2   -i hw:0,0   -s 1024x768 -f x11grab -r 30  -i :0.0
-acodec pcm_s16le -vcodec libx264 -vpre lossless_ultrafast -threads 0
output.

if Input source is using [Audio Mixer], the driver may need to unmute
only the seleted source and the other sources may need to be muted
