After some digging, I found this message:

NVP : : AddAudioData():p1: Audio buffer overflow, audio data lost!

I am using ALSA, as it is the default in the Fedora Core kernel that  
I have.

Could this be a performance issue? I ran this machine with 256MB of  
RAM for months, and it didn't have any problems. Now it has 768MB,  
and a whole lot more hard drive space (recently added another 400GB  
to LVM). So I am not sure why there would be an overflow problem.

Thanks again.
