Hi!
I tried (successfully) to install F17 in my asus 1215B netbook in an external USB hard drive (including the bootloader). Almost everything worked out of the box (except for a few functions keys and little things like that), but I tried to install AMD propietary drivers. After a few tutorials I could do it without problems. BUT when I went back to Windows a funny thing happened. If I plugged in the headphones, I had no sound at all but if I unplugged them, the audio worked ok. So I went to fedora to check the audio and it worked flawlessly... I tried everything: reinstall audio drivers in windows, restore Windows to a previous state, change audio settings... nothing worked, so I went to bed wondering WT* was happening.
The next day I turned on the laptop and the audio in Windows worked fine... WHAT?? I didn't do anything!!... So I forgot about it.
I start Fedora again and upgraded it and after that, fedora didn't boot properly. After the loading fedora logo, I got a black screen and that's all. So, I started it in text mode, I uninstall AMD drivers and reinstall the original ones and fedora booted ok again but it consumed a little bit more power than before so I reinstalled the propietary AMD drivers and this time everything looked fine. After that, I started Windows and, you know what?? Yes, the headphones had no sound!! WT***UUUCK!! So I reinstalled the graphics drivers in windows with no luck (I thought if the AMD grpahics drivers in Linux is messing with Windows, try to reinstall them). Nothing, the problem didn't go away. I rebooted the system a lot of times, trying one thing after another until I started to think. What did I do differently yesterday? I turned off the computer. Ok, let's do that. And voilá, it worked!! So, after installing propietary AMD drivers in Linux, you can reboot all the times you want an asus 1215B... the problem with the audio in Windows doesn't go away until you actually turn off the computer!
Maybe the linux drivers change some flag in the hardware that is not reset until you turn off the system... I don't know.
I spent like 3-4 hours in total with this problem, so I'm posting this to prevent other people to waste their time in case this happens to someone else.
If you know what's happening, I'd love to know
