Title:
Repetitive sound distortions when voicechatting on Skype
Status in Ubuntu:
New
Bug description:
I am experiencing serious repetitive sound distortions when
voicechatting live on Skype (also on Google Hangouts). Once the
distortions start, they don't stop.
The distortions manifest themselves as a series of choppy, repititive
sounds which pick up on small segments of audio from the conversation
I am having which change every 10 seconds or so. The person on the
other end often hears nothing when it starts. It happens regardless of
whether it is a Skype-to-Skype chat or if I am calling a phone number.
It doesn't happen every time. Sometimes, it goes away on system
restart.

I always use Skype's Echo Testing Service to check for any sound
difficulties. At the moment, it is producing exactly the sound issues
as reported above. If it doesn't, I proceed to try to voicechat.
Clearly, I expect to hear audio without any such distortions after
launching Skype.
Thanks very much in anticipation of any help you can provide to fix
this irritating issue!
