This is a weird question, but it is really happening. I was watching Breaking Bad in the totem player, and Walter White's voice was sounding slightly higher than normal. It wasn't enough for me to think twice about it.
I also noticed it when I was watching YouTube. Everyone's voice is higher whenever I am playing sound.
I have absolutely no idea what could cause this, and I do not know how I could provide information on my Ubuntu settings that might cause this. Does anyone have an idea of what this may be? I am assuming it is happening with all audio, just only noticeable with people's voices. If there is something else I can add here to help you answer this question please let me know.
I am using Ubuntu 13.04
