As per RHBZ 1321266: https://bugzilla.redhat.com/show_bug.cgi?id=1321266
Recent Fedora kernels for F23 have disabled the CONFIG_ACPI_REV_OVERRIDE_POSSIBLE option. This causes a regression on Dell XPS 13 (9343) -- severe problems with audio playback in I2S mode. This is clearly a regression -- audio worked correctly on previous kernel releases. Without the APCI override in the kernel, sound playback in I2S mode on XPS 13 is broken, due to multiple problems (such as missing ALSA configurations). -- devel mailing list devel@lists.fedoraproject.org http://lists.fedoraproject.org/admin/lists/devel@lists.fedoraproject.org
