Not sure if this is just a problem I'm having, but it started ever since i installed U30. It doesn't happen very often but when it does it certainly lets me know.
Ill be driving along and the sound will make this horrible sheering/screeching noise, like you're using a power saw to cut through a lump of metal. The first time i heard it I nearly had a heart attack
I use headphones, so when it happens its very very loud and I usually get all paranoid that the aliens are here to beam me up or send me weird messages via LFS.:alien2:
And once this happens the sound will be gone completely, or it becomes really quite. If I hit SHIFT + W to reinitialize the sound nothing happens and it still continues, its like it does it when it wants too. It doesn't give me any warning signs or indications when its going to do it either!
