Here's what I did to get my sound/microphone working. It appears ubuntu is loading the wrong module for our soundcard at start so some people dont get sound or get to use their microphone.
Manually load the module as so. sudo modprobe snd-soc-rt286 goto your sound settings in the system settings and choose your output device and sound should immediately start working as well as your microphone. you want to have the module automatically load at start up. sudo nano /etc/modules add this to the file and save and close it: snd-soc-rt286 restart your system to make sure sound is working automatically after reboot. now enojy your sound! -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1413446 Title: Audio broken on 2015 XPS 13 (9343) in I2S mode in Ubuntu 14.10/15.04 Status in Dell Sputnik: Invalid Status in HWE Next Project: Invalid Status in linux package in Ubuntu: Won't Fix Status in linux package in Fedora: Unknown Bug description: (This is a public bug report for LP1402828.) This system has a dual-mode audio with an HDA and an I2S interface. Which shows up depends on the reported _OSI from the last cold boot. Since the kernels in Ubuntu 14.10/15.04 (15.04 uses 3.18 currently) report an _OSI of "Windows 2013", I2S mode is used for audio. A workaround is to pass acpi_os="!Windows 2013" as a kernel parameter, but this is non-optimal since the mode of the touchpad is affected. It also results in an alternate, less used and tested path in the firmware to be used. See the attached dmesg log for details on where the failure happens.
