I had this problem on a Fujitsu Siemens Amilo computer. I solved the problem by installing the latest Alsa driver (see instructions at https://help.ubuntu.com/community/HdaIntelSoundHowto). Maybe this is unnecessary. Then I used cat /proc/asound/card0/codec\#*|grep Codec with result
Codec: Motorola Si3054 Codec: Realtek ALC883 then went to http://www.mjmwired.net/kernel/Documentation/sound/alsa /ALSA-Configuration.txt and searched for ALC883 and found many options. Luckily, someone else tried them for me; and found that adding options snd-hda-intel model=acer to the end of the file /etc/modprobe.d/alsa-base and restarting the computer fixes the problem. I found that, finally, the contents of gnome-volume-manager changed and that the headphones were working! -- snd_hda_intel (alc883 chipset) does not perform jack sense https://bugs.launchpad.net/bugs/114053 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
