This article assumes that the modem is functional in other respects besides not providing audio feedback during the course of the connection sequence, which typically proceeds through a brief dial tone, then the usual touch tones as the telephone number is dialed, and finally the modem handshaking tones (squealing, static, and so forth). If all of this audio feedback is absent, but the modem otherwise works, proceed as follows:
- Open the Monitors & Sound control panel and click on the "Sound" button at the top of the control panel.
- Adjust the "Computer System Volume" slider such that it is at a level at which the system beep can be heard distinctly (the system will beep each time the slider is adjusted).
- Click on the "Sound Monitoring Source" pop-up menu and ensure that "Internal Modem" is selected. The audio feedback from the modem should now return.
