I just installed a fresh Fedora 21, my system is now up to date.
Now, my problem is that my integrated microphone is not working.
I tried several different fixes that doesn't work (install and manage sound with pulseaudio, change settings in alsamixer, ...).
I don't know what to do now :/
I have got a Dell XPS 15 Laptop with Fedora 21.
Thank you !
