My clutch pedal is making some noise when I upshift. It's a buzzy rattle that happens near the top of the clutch travel. If I take my foot off the clutch pedal it goes away, but the next time I shift I hear it when I am letting the clutch out. At first I thought it was the speaker in the driver's door making noise, but then I noticed it when using the clutch.
I also have this weird thing that happens with the sound of the radio. Sometimes it sounds very washed out, almost monotone. I also hear that weird high-pitched sound sometimes when listening to the satellite radio -- you know the sound when you are streaming something other the internet and it doesn't quite have enough bandwidth so the sound quality goes down. Both of these issues come and go, so part of it could be how the signal is being picked up (in an area with weak signal, interference with CB radios, etc).
