The first thing you should do is remove the 'options snd-hda-intel model=dell-m6-dmic' line you added to /etc/modprobe.d/alsa-base.conf file (dell-m6-dmic is not a valid model name for the Realtek ALC889 codec).
If you continue to experience the issue after rebooting, please attach an updated alsa info: https://wiki.ubuntu.com/Audio/AlsaInfo ** Summary changed: - [, Realtek ALC889, Green Headphone Out, Front] No sound at all + [Intel DX58SO, Realtek ALC889, Green Headphone Out, Front] No sound at all -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1099167 Title: [Intel DX58SO, Realtek ALC889, Green Headphone Out, Front] No sound at all To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1099167/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
