Speakers stay on in Ubuntu 12.04 when headphones are plugged into the jack. (Fujitsu T2010, ICH8 chipset, ALC262 audio). All was working fine in 11.10. /etc/modprobe.d/alsa-base.conf contains
options snd-hda-intel model=fujitsu which used to be working before.
I submitted a bug report (https://bugs.launchpad.net/ubuntu/+source/linux/+bug/997420), but in the meantime I am looking for an acceptable solution. Right now I can't use my laptop to listen to music or watch videos in public places, which is very frustrating.
Is there some workaround that will allow to mute the speakers while listening to the headphone output?
