[ubuntu] [SOLVED] Need to remove Audacity from 8.04

[CyberDean]

Just received the below Visionman DEP-VO100 Intel computer for audio recording at church. Installed Ubuntu 8.04 64 bit desktop and Audacity.
When I record audio there is a tone under the audio I am trying to record and it is distorted. When I installed Audacity, I compiled it like I did on my desktop that we currently use without any problems. I would like to remove Audacity from the computer and install the precompiled version to see if there is a difference in recording quality, or maybe a bad audio circuit. But I can't figure out how to remove the current Audacity. Synaptic Package Manager and Add/Remove do not see it as being installed. I have searched through the directories and can not find a directory or file for audacity. The program "Audacity Sound Editor" is listed under "Applications", "Sound & Audio". The only other thing I can think of is to wipe the disk and start all over, that would not be a big lose, very little data on the computer at this time.

Any help out there? Thanks in advance.
