You call a friend on Skype, tell him something, and in response - silence. The problem can be both with your speakers and with the microphone of your interlocutor. You need to set up your accessories to work correctly.
In order to properly configure Skype, you need to check the hardware, settings in Windows and in the program itself on both computers - on yours and on the interlocutor's PC.
Setting up your computer
On your part, you need to check if the built-in speakers, speakers or headphones are working. Make sure that the device is properly connected to the computer and that it is turned on. And first you need to find out - does the sound work outside of Skype? Just turn on music or a movie on your PC, and if the sound is heard, then the problem lies elsewhere. If there is no sound, then you need to update the sound drivers. You can install them using the disk that comes with your computer / laptop or download it on the manufacturer's official website.
After that, you need to go to the sound settings in Skype ("Tools" - "Settings") and select the desired device in the "Speakers" line. If there are several of them, experiment. There is a sound test button next to it, with which you can verify that the sound is working. After saving the settings, you need to select the Echo / SoundTestService contact and make a test call. The robot will help you make sure the sound is actually working.
If everything is in order with your speakers (headphones), then the problem exists in the system of your interlocutor.
Configuring the interlocutor's computer
If in your case the problem could be with the speakers, then your interlocutor has a problem, most likely, with the microphone. You need him to check if the microphone is securely connected to the computer. The device may have been connected to the wrong connector (the microphone connector is usually located on the back of the system unit and is pink).
After that, you need to make sure that the microphone is turned on. During a conversation in Skype, in the conversation window there is a button with a microphone, with which you can turn the device on and off. If this icon is in a red crossed-out square, it means that the other person accidentally muted their microphone. To turn it on, you need to click on this button again.
You can check if the microphone is working in the settings of the program itself ("Tools" - "Settings" - "Sound settings"). You can also test the device through a test call to the robot.
If you encounter problems such as distorted or intermittent sound during a call, follow these steps. To begin with, you need to quit Skype, then through the "Start" menu select the "Run" command. In the window that appears, enter "% appdata% / Skype" and press Enter. The Skype folder will open, where you need to delete the shared.xml file. After restarting the program, the sound problems should disappear.
