Note: After a complete system re-install my audio had been working fine: **Stock kernel/Intel VGA/GDM/Gnome**
Then the problem re-occurred after I did some work with an alternative stack: **Stock kernel/Nvidia/lightdm/Gnome** and then switched back to my original stack. **Perhaps lightdm does some dodgy low level configuration? Or perhaps it's something to do with using Nvidia (with prime-select nvidia)?** (if you're wondering why I'd change my DM for a session it's because nvidia drivers + gdm = dead system. See https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1559576 so when I need the nvidia stuff for OpenCL support in Darktable I have to switch DMs.) Back on the original stack, the command line fix in comment #7 worked for me on 4.4.0-24-generic after unplugging and re-plugging in the jack. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1575078 Title: [XPS 15 9550, Realtek ALC3266] Headphone jack stops working after a while To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1575078/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
