Loco4chat messes with your Ventrillo settings so you get exactly what you describe and the "funny noises" from Loco4chat can be heard by other players.
You need to reset your basic sound settings for Vent:
Basic Sound System Setup
(Windows XP)
Go to Control-Panel / Sounds & Audio Devices / Audio tab / Volume button / Select "Options" in the menu / check "Advanced" / select "Properties" / select "Playback" radio button / check all boxes
select "Record" radio button / check all boxes / click OK
In the playback list of devices - check the "Mute" box under Microphone. Close window
Click the Volume button in the "Sound Recording" section. If the check boxes display "Select" then check the box under Microphone. If the check boxes display "Mute" then check all boxes EXCEPT "Microphone" and "Mute All"
(Standard set up from Ventrilo forums)

If no help, try a System Restore from a date before the problem started.
This reference may be of help concerning "feedback" in general.

I assume you did not change any of the cable jack inputs to speakers, mic, etc.
