Changing the Alert mode on each knob position from Silent => Tone worked for me. I did notice my G4 crash on me and reboot after making this change (believe it was when I switched channels).
I ended up creating another fresh G4 profile using the new PPS. One of the things I noticed is the Talk Group Lists on the knob positions:
In the newly created profile they are display in the format of:
TAG + (TGID) +

In the profile that was converted from the old PPS version they are in the format of:
TAG + (TGOD) + [T

When running the "fresh" config I created with the new PPS the G4 has yet to crash now. I suspect some of the other reports of rebooting others have experienced might be related to profiles that got corrupt when PPS updated them.
