I am using Arch Linux 32 latest version on Sony VAIO VGN-FS215Z . The following is the audio device:

-fs215z:~$ lspci | grep -i audio

00:1b.0 Audio device: Intel Corporation 82801FB/FBM/FR/FW/FRW (ICH6 Family) High Definition Audio Controller (rev 03)

When I boot the system after some time getting crackling sound in speaker. Sometimes it stops after few minutes and sometimes continue to sound. Really annoying. I am not getting the normal audio in any application. This problem was there in debian based OSs also but not there in any other OS.

Please help.
