crackling sound in Debian Sid 64bit

In current Debian Sid / Wheezy, Skype sound output through pulseaudio is crackling and audio input is outright atrocious, i.e. crackling in the extreme. All other sound applications work just fine.

 

At the same time, sound in Debian Squeeze is ok and to my surprise, it also works well in current Ubuntu. So there must be some specific reason why Skype misbehaves on Sid / Wheezy.

 

My ~/.asoundrc goes:

 

pcm.!default {
    type pulse
}
ctl.!default {
    type pulse
}


So Skype uses pulseaudio, however, the result is very disappointing...

I am having a similar problem and the last version not to cause the problem on both Linux mint 12 and debian testing for me is 2.1.0.81

Re: crackling sound in Debian Sid 64bit

I have just followed the guidance for the first fix on this page and the sound now sounds great.

 

http://www.pc-freak.net/blog/how-to-fix-pulseaudio-and-skype-crappy-sound-glitches-choppy-sound-and-crackling-on-debian-gnu-linux/

 

In summary

 

In file/etc/pulse/default.pa its necessary to substitute the line;

load-module module-udev-detect

 

with

 

load-module module-udev-detect tsched=0
