Read through the topics and I don't think anyone has mentioned this bug yet. When you set in game sound to zero, it remains silent even though you increase the volume. For example, if you set volume to level 0 and increase it to Level 1, Level 2, ect., you will hear nothing. The only way to get back sound again is by decreasing the volume (like from Level 2 to Level 1). Minor, but I find it annoying sometimes as I often use in game volume controls.
Realized I posted in the wrong topic earlier. Was able to delete my post. Sorry about that...
