Ok. I recently hooked up my HP laptop to our church soundboard to start recording our am/pm services. However, I am not getting a clear recording because the built in mics on my laptop are picking up sound on top of the lapel mic. How do I turn the laptop mics off and still record through the lapel mic? I have tried everything I can think of, but when I mute or disable the built in mics it will not record the lapel mic.
