Some interesting update. The card worked for last 5 months without issue on Windows 10, and worked under Gentoo(I installed gentoo 1 week ago) until I started plugin-in the headphones. It worked like this about 5x times and then the sound stopped working at all. The device was visible, but unusable under Linux and Windows. I tried to disable Audio in BIOS and rebooted, but no luck (few times).
Then today I was updating my drivers under Windows again and also flashed the BIOS with latest one (strange was that the version installed was same as new proposed, but number of features was different). Anyway I pickup the install, flashed the BIOS and voila the sound card is online and working :-) I didn't do screenshots, but if this will happen again, I will try to do some more data capture. So in general I got to situation reported by some other users which were asking Dell to replace audio card at all in the past (I was saying my wife that I will do the same this morning), but finally BIOS flash helped. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to alsa-driver in Ubuntu. https://bugs.launchpad.net/bugs/1575078 Title: [XPS 15 9550, Realtek ALC3266] Headphone jack stops working after a while Status in alsa-driver package in Ubuntu: Confirmed Bug description: I'm experiencing a strange behavior with a headphone jack on my laptop. I have an external audio speaker connected to it. When I disconnect the speaker and reconnect it again it stops working. Even more, laptop audio stops working too. And after the reboot, I don't even see any of the audio devices. I've googled a lot and tried different fixes from forums with no luck. After a while, I've accidentally discovered that putting the laptop to the sleep mode and rebooting system after brings audio back to live. Even more, if speakers were attached during this sleep-reboot procedure, they are starting to work as well. However, after the next reboot speakers are not working again. And if I will plug them out and in - problem with completely missing audio returns. P.S. I'm using laptop-mode-tools package on my laptop. Recovery after hibernation made me believe that it's somehow related. But after uninstalling this package nothing really changed.
