Comment 15 for bug 819699

I have got Toshiba Satellite T110-10Z and I am also affected by this bug. Found workaround here which works: http://ubuntuforums.org/showthread.php?p=10532125#post10532125

Simply add a line to /etc/modprobe.d/alsa-base.conf:

options snd-hda-intel model=hp-laptop

Several bug reports have been opened and resolved by (diwic) for different laptops but same Conexant codec.
