Try this just to make sure nothing got reset to default
Go to system prefs/sound and switch from internal speakers to the soundsticks.
Let me know the outcome please
That is the issue then....do you have your soundstick drivers
make sure you have all the updates downloaded for your new version of MAC OS they might have the new drivers
I will look for the drivers ...what is the exact model of Soundstick?
go to the site above this will show you the path to update all the software you have on your mac. There are no updates for the sticks...the way to update on a mac is with the mac updates.
Let me know what happens
