I have been using skype perfectly for over 2 years now. I haven't changed headset or anything like that, however people can't hear me when i call them?
When i call the echo sound test i cannot hear myself, but if i go to "adjust microphone settings" i can infact hear myself?
Try to reset Skype settings.
Quit Skype or use Windows Task Manager to kill any Skype.exe process. Go to Windows Start and in the Search/Run box type %appdata%, press Enter or click the OK button. The Windows File Explorer will pop up. There locate a folder named “Skype”. Rename this folder to something different, e.g. Skype_old. Restart Skype.
N.B. If needed, you will still be able to re-establish your call and chat history. All data is still saved in the Skype_old folder.
I was just use it last night and it was fine. Why all the suddent this morning is not OK? My brother use it yesterday morning, had a same problem. But he did not have the problem the night before. It's all happen in the morning. I wander has to do with cable internet. I used sound check. And it says my microphone is fine.
