This problem persists for me also on my Asus V1S. WORKAROUND !!
I followed this workaround and now my headphones work as expected: http://ubuntuforums.org/showthread.php?t=582089&page=2 Basically * Add/change the following line in /etc/modprobe.d/alsa-base: "options snd-hda-intel model=lenovo" * Go to System > Settings > Audio > choose Device: HDA Intel (...) and Channel: PCM * If you use the applet in the gnome-Panel to control the volume: Go to [right click] -> Settings -> Device: HDA Intel (...); Channel: PCM * You may want to turn up the volume of the Front channel to almost 100% * Reboot This is not fix but it does make it work. -- Laptop speakers won't mute when using headphones https://bugs.launchpad.net/bugs/92992 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
