Can not hear from earphone on fedora linux ALSA Conexant

1. check if the file /etc/modprobe.d/alsa-base exists, touch an empty one of this if not.


2. add following line to it :
options snd-hda-intel model=olpc-xo-1_5


3.save and reboot.


Then the problem should have gone.


Note that this may only do the tricks for exact this sound device
"Codec: Conexant CX20583 (Pebble HSF)". If it is not working for you, please refer to the original post at http://linux.derkeiler.com/Mailing-Lists/Ubuntu/2010-05/msg00541.html.
