Did the MyLink upgrade on my 2012. Everything works fine except I have no sound. No chimes or signal sounds. Any clue why?

I wouldn't say everything works fine then....

Sorry man but that one cracked me up too.. "everything is fine except it doesn't work anymore".
hehe... sorry! but it's funny, you have to admit.
Unfortunately I also have no useful knowledge to share either.

Just to be sure, you have music but no blinker sounds etc?
If so, this may help:
