If you're using the 3.5 kernel you need the dkms-hda-lts-quantal package instead, quoting https://wiki.ubuntu.com/Audio/UpgradingAlsa/DKMS
"Note the difference between the quantal version dkms-hda and the precise version of dkms-hda-lts-quantal : If you're running Ubuntu 12.10, you should use dkms-hda of quantal, whereas dkms-hda-lts-quantal of precise is for users of Ubuntu 12.04 that are running the backport kernel (the linux-image-generic-lts-quantal package)." -- 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/960124 Title: [VPCZ13C5E or VPCZ114GX, Realtek ALC889, Speaker, Internal] No sound at all Status in “alsa-driver” package in Ubuntu: Triaged Bug description: Sound works with my headphones plugged in.
