I am also having this problem on a Dell Precision 5520 (which is similar hardware to both the Dell XPS 15 and Dell XPS 13).
Headphone output worked initially since install and then stopped working mid-session after unplugging and re-plugging the headphones. I was adjusting the "Alert volume" setting in sound settings at the time, which may or may not be relevant. Reebooting, unplugging and replugging, etc, nothing seems to bring it back. I am on Ubuntu 17.10 having installed fresh at the time of Beta 2, and the problem started occurring whilst I was fully updated today. -- 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/1721537 Title: No sound from headphone jack on xps13 9350 after ubuntu 17.10 dist- upgrade Status in alsa-driver package in Ubuntu: Confirmed Bug description: I just upgraded from 17.04 to 17.10 on my Dell XPS13 9350. Ever since my headphone jack doesn't output anything. The internal speakers are still working fine, the speakers I connect to the laptop too (tested with my phone). The system does recognize the speakers being connected, since I get the Headpones | Headset | Microphone popup and I can also test left/right speakers in Sound. However, no audio is coming through.
