Uploaded audio and/or connect tone playing over computer speakers instead of through the TCA Modem

1. Right-click the volume control icon on your task-bar and select "Adjust audio properties." Then, select the audio tab and ensure the default playback and recording devices are set to your sound card and not "UAC3556B." Sometimes Windows XP assigns the TCA modem as its default audio playback device, which re-routes the audio WinLink is trying to play to the sound card, since Windows has assumed control over the TCA.
