I never experienced this during Fallout 3 but is anyone else hearing a strange buzz sometimes will playing New Vegas, especially while using the pipboy ? Is there a way to remedy this ?

I've been having the same problem... or at least a similar one.

Originally, I was suffering from EXTREMELY delayed sound and environment effects... so much so that, up to five minutes later, I would hear my gun fire. Crazy! I did find a fix, partially, but as you said... now there is a strange buzzing sound. I -believe- it is the environmental ambiance 'looping' over the top of itself or stuttering insanely... but I can't really tell.

All I know is that it's annoying... and hope that someone can find a fix.

You sure it's not Ed-e?

The background buzz inside the PipBoy is intended. It can be modded out.
