I have just installed Skype, so my wife can keep up to date with our new grand daughter in Cardiff. Got a Logitech C270, amazing little webcam. Everything works fine, or so I thought. Every now and then a very noisy whooshy/crackling sound comes up and my daughters incoming sound goes, she can still hear me, after 30 second or so everything is fine again for a while, then it happens again. I have done all the tests, and everything works. We both installed Logitechs Video HD software, and get the same problem using this. I have checked on the web and sound faults seem to be quite common in Skype, but no definitive solutions!!!!!
Any ideas much appreciated.
Thanks

If you have Skype 5, downgrade to Skype 4.2 or Skype 3. Skype 5 is very unstable and has been the number one source of issues when I had it for a short amount of time.

Beware that 4.2 has a forced auto-update. You have to block the IP address of the update server in your Windows Firewall to prevent updating. Skype 3 does not, but it also doesn't have newer codecs.

Thanks for that Jack, will give it a try. But I dont think its a Skype specific problem, We uninstalled Skype and installed Logitech's own "Video HD" software. Exactly the same. Very annoying
