i have a Fujitsu S7110 and i have no sound (speakers or headphones)
after i restart on battery. i find that happened because on battery the
sound sistem are somehow deactivated. a workaround is this:
1. sudo nano /etc/rc.local
2. insert the following lines before exit 0:
echo 0 | tee /sys/module/snd_hda_intel/parameters/power_save
echo N | tee /sys/module/snd_hda_intel/parameters/power_save_controller
pkill pulseaudio
pulseaudio --start
3. reboot
the solution is adapted from someone who make exactly the reverse.

Title:
[Fujitsu S7110,ALC 262] Not sound/ Speaker issue 12.04
Status in “alsa-driver” package in Ubuntu:
Confirmed
Bug description:
I am having critical sound issues since I did the update to 12.x and I
have been looking on many post to find solution without success.
I am using a laptop Fujitsu S7110 and just did a fresh install 12.04.
I did the standard OS update after running the fresh install from the CD and
I don't get any sound from the speakers.
The Alsa log file can be found here:
http://www.alsa-project.org/db/?f=83443eabc64a7d840001f687e9a8634df57226b1
I am kind of desesperate about this bug and might switch (after
several years of using Ubuntu) to an other distribution.
Any help would be welcome.
Best regards,
David
