dmesg from kernel 4.5.5
Should be fixed in the next build. With the rebase I accidentally dropped CONFIG_DW_DMAC_CORE=y (because it's actually a terrible hack but upstream made a poor choice requiring that for sound on these platforms). kernel-4.6.4-301.fc24 has been submitted as an update to Fedora 24. https://bodhi.fedoraproject.org/updates/FEDORA-2016-9a16b2e14e kernel-4.6.4-301.fc24 has been pushed to the Fedora 24 testing repository. If problems still persist, please make note of it in this bug report. See https://fedoraproject.org/wiki/QA:Updates_Testing for instructions on how to install test updates. You can provide feedback for this update here: https://bodhi.fedoraproject.org/updates/FEDORA-2016-9a16b2e14e kernel-4.6.4-301.fc24 has been pushed to the Fedora 24 stable repository.

Created attachment 1175145 [details] dmesg from kernel 4.6.3 Description of problem: The Dell XPS 13 9343 sound card is undetected in kernel-4.6.3 while it is detected and functions properly in kernel-4.5.5 and kernel 4.5.7. In 4.5.* the sound card appears as broadwell-rt286 along with an HDA Intel HDMI sound card where as in 4.6.3 only the HDA Intel HDMI sound card is detected. Version-Release number of selected component (if applicable): kernel-4.5.5-300.fc24.x86_64 (working) kernel-4.5.7-300.fc24.x86_64 (working) kernel-4.6.3-300.fc24.x86_64 (not working) How reproducible: Steps to Reproduce: 1.Boot kernel-4.6.3 and go into gnome control panel's sound section or alsamixer "select sound card" and see that broadwell-rt286 does not appear nor any other functioning sound card name. 2. boot kernel-4.5.5 and/or 4.5.7 and go into both or either of the aforementioned locations and see that broadwell-rt286 does appear and is functional. Actual results: Undetected and thus non-functioning sound card Expected results: Detected and functioning sound card Additional info: (dmesg | grep "XPS 13"): [ 0.000000] DMI: Dell Inc. XPS 13 9343/0TM99H, BIOS A07 11/11/2015
