but I had no luck.
This also happened to me when I upgraded from Hardy to Intrepid. Back then, I fixed it by following the instructions in this post:
but the article it links to is no longer there I don't quite remember what it said, but all it did was get my speakers back. However, I do remember that after about a week or so, they fixed everything in an update.
I'd be willing to just try a fresh install if anyone could confirm that it has worked on a gateway. If you have any luck though, please let me know
