I've found a couple of times that my audio wasn't working when going back to HDA mode after using I2S mode. I can get it back by opening a terminal, launching alsamixer, pressing F6 and selecting the "HDA Intel PCH" device, then using the up or down arrow to adjust the master gain.
I have no idea why this is necessary, but after doing it once it isn't needed on subsequent reboots (unless I've changed to using I2S audio in the interim). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1413446 Title: Audio broken on 2015 XPS 13 (9343) in I2S mode in Ubuntu 14.10/15.04 To manage notifications about this bug go to: https://bugs.launchpad.net/dell-sputnik/+bug/1413446/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
