i'm not sure why, but it seems my volume controls have fallen apart. my alarm clock wasnt going off, since my alarm volume was set to zero, which i come to find out can only be adjusted in the alarm tone selection menu. now my system sounds volume is off, and i'm not sure where to go to up that (i.e., no audible clicks for selections despite the fact that it is turned on). i assumed the system sounds were tied to ringer volume. i could have sworn that when turning my ringer down, my system sounds made an equal adjustment. did my system sounds somehow unlink?
