With Fedora 15 64 bits, all updates installed, i have no audio with headphones. the audio works fine with laptop speakers, but when headphones jack is inserted the audio continued from the laptop speakers and no from headphones. with older fedora and ubuntu editions there is no problem with headphones audio output.
this is a gateway nv53 laptop.
In ubuntu 11.04 I solved the problem adding two lines in /etc/modprobe.d/alsa-base.conf:
options snd_hda_intel model=laptop
options snd-hda-intel position_fix=1 enable=yes
But in Fedora this file does not exist
thanks for any help.
