My five cents:

I just upgraded to Kubuntu 12.10 beta 2 AMD64 with full updates and the
awful cracking/echoing noise is still present in both VLC 2.0.3 and
Skype 4.0.0.8 x64. My system is AMD based with 785G chipset.

* The ¨rm ~/.pulse -rf¨ worked only for seconds until I closed and
reopened VLC; no changes in Skype.

* The solution at #23 solved inmediatly the cracking for both apps.

On any case I'm still scared of how OLD this problem is. Come on, we are
in 2012 and this thing is still chasing us five years later. I'm sure
there is someone we can write an email or something to fix it
FOREVER....

Regards.

PD: If I find some change will post back. ;-)

Title:
  pulseaudio distorts VLC audio

Status in “pulseaudio” package in Ubuntu:
  Confirmed

Bug description:
  Binary package hint: pulseaudio

  Audio quality full of hiss (similar to what it might sound like if you pulled 
your headphone/speaker plug out halfway). The hiss distortion is constant and 
affects all VLC 1.1.8 audio. True for all audio sources: internet stream, mp3, 
cd, flv, etc.
  Problem occurred on a clean install of Ubuntu 11.04 beta (32-bit)  using only 
the included repositories, and updated as of today's date. Pulseaudio version: 
1:0.9.22+stable-queue-24-g67d18-0ubuntu2
  Disabling pulseaudio allows VLC to play cleanly. Have not observed audio 
distortion with other players using pulseaudio.
  Would like to see VLC operate properly with pulseaudio. I had no issues on 
same machine using Ubuntu 10.10 and VLC 1.1.4.
