Cant Hear Sound After Call Is Answered

I'm using US Robotics Sportster Voice 33.6 Faxmodem.

When I call, the program answers after 2 ring calls, but I can't hear the files, and I stay connected while the program seems to consider the call hanged (see log below). Do you have any idea what might cause this problem ?

I'm on XP sp1.

Thanks for your answer.

The trace is showing that the playing of the sound files is handed off to the Wave drivers, and if you are not hearing the sound file this indicates that the wave drivers are playing it on the wrong output device...

We have seen this happen before - wave drivers sometimes get a bit confused as to which device should be used for playback when there is more tehn one output device available...
The way to resolve this is to uninstall or disable all the other wave drivers and install the modem drivers first... and then install the sound card's wave drivers.

If your sound card auto installs using PnP then I'd try disabling the sound controller using the Control Panel -> Sound and Multimedia Properties applet.
Select Hardware tab, highlight your sound card, click properties and select 'disable' at the bottom of the window.

(above is for Win2000, but similar can be done in other versions of Windows)
