Just to make sure I understand. I have to add at the end of /etc/modprobe.d/alsa-base
options snd-hda-intel model=3stack save and reboot and try if it does not work I add instead options snd-hda-intel model=3stack-dig and so on until it works. I have tried 3stack, 3stack-dig, and auto. None of these 3 work. I have also installed Gnome Alsa Mixer. For me it would be ok to disable the PC speakers for ever. I will continue with 6stack-dig, 3stack-660 3stack-660-digout lenovo dallas hp if I am doing right. -- Headphones and laptop speakers work simultaneously https://bugs.launchpad.net/bugs/297864 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
