I've experienced plenty of problems with Pulseaudio and Skype output sound hell crappy. This stupid proprietary program Skype is a total crap … Anyways again thanks to ArchLinux's wiki, I've used the two mentioned steps to fix all this Skype in / out problems …
1. Fix problems with Glitches, voice skips and crackling In file /etc/pulse/default.pa its necessery to substitute the line;
load-module module-udev-detect
with
load-module module-udev-detect tsched=0
2. Resolve Choppy sound in (Pulseaudio) -> Skype
In /etc/pulse/daemon.conf two lines has to be also substituted:
; default-sample-rate = 44100
Should become;
default-sample-rate = 48000
3. Change /etc/default/pulseaudio to allow dynamic module loading
It is a good idea to the default settings from DISALLOW_MODULE_LOADING=1 to DISALLOW_MODULE_LOADING=0 .This step is not required and I'm not sure if it has some influence on solving sound in / out problems with Skype but I believe it can be helpful in some cases..
So in /etc/default/pulseaudio Substitute:
DISALLOW_MODULE_LOADING=1
to;
DISALLOW_MODULE_LOADING=0
4. Restart PulseAudio server
After the line is changed and substituted a restart of PulseAudio is required. For PulseAudio server restart a gnome session logout is necessery. Just LogOff logged Gnome user and issue cmd:
debian:~# pkill pulseaudio
This will kill any left pulseaudio server previous instances.

One other thing, that is said to help to microphone have a reduction of noise is muting the Microphone boost using:
View Comment$ alsamixer
I’ve disabled it myself, but I’m not sure if mic input is better now. It could be helpful only tome sound cards.
thanks! … it worked on Skype 4.0 on Linux Mint 13 (Ubuntu precise should work also)
View CommentI’m glad it helped. Also problem seems to be solved on Xubuntu 12.04. I will be glad to hear if it works on other distros too.
View CommentThanks, worked!

View CommentHi check in my Skype section. There I have few articles on problems I experienced with Skype microphones. Also it strongly depends on Skype version you need for me 2.0.x Skype works good.
View CommentWhat skype version you use?
View CommentThe note about killing the pulseaudio daemon (forcing it to restart) solved a different problem for me (Linux Mint Xfce on an older MacBook Pro).
Thank you,
John
View CommentMany thanks for the tip on removing the crackling audio output. The "tsched=0" addition was successful in fixing the sound on my Dell Vostro, with Debian Wheezy installed.
