Modem audio streams

To check whether your voice modem driver is correctly installed, you can check the modem voice streams are correctly recognized by Windows. If either one is not installed correctly, Voicent program might failed to start, or failed to play audi files.

Go to Windows Control Panel > Sounds and Audio Devices, select the Audio tab. Please make sure “Modem #x Line Playback” is listed under the Sound playback box, AND “modem #x line recording” is listed under Sound Recording box.

Please don’t change the settings. Click Cancel when done.

If either of the audio stream is not listed, you need to reinstall the modem driver.
