I had this bug ever for several years, ever since installing ubuntu on an Advent 5411, over several different versions including 10.10 and 12.04 (current). Previously, if I wanted to use headphones on this machine, I had to use an external USB sound card.
After confirming this bug, I did a little more googling regarding SigmaTel STAC 9205 Headphone Jack problems and found a fix in this link: http://ubuntuforums.org/showthread.php?t=1219505 In my case (12.04), this was a case of editing /etc/modprobe.d/alsa- base.conf to add the following line at the bottom: options snd-hda-intel model=eapd position_fix=1 Followed by a reboot. This fixed the problem for me and now I can use the headphone jack for the first time ever. Hope this helps someone. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to alsa-driver in Ubuntu. https://bugs.launchpad.net/bugs/668030 Title: [SigmaTel STAC9205] Playback problem Status in “alsa-driver” package in Ubuntu: Confirmed Bug description: I have an ADVENT 5411 laptop. When I play music, the laptop speakers work fine but when I plug in headphones I cannot hear any thing. First I thought it was a problem with headphone jack but it works fine in windows OS. I had this problem with the previous version (10.04) and now in 10.10. Any help would be appreciated.
