After installing PB2, I don't get a system sound when pressing the sound up and sound down buttons. I do get the transparent icons onscreen, but no sound to go along with it. I get sound from any media just fine. Anyone else with this issue.......OR is this a new thing to be turned on or off in Sys Pref? ---------- answered my own question. There is a tik box in the Sound Preferences area for this. I don't know if it existed in previous builds, but it is there and OFF by default. Glad it's there, I hated that before, so now I have it off.
