This was initially filed as a kernel bug: https://bugzilla.kernel.org/show_bug.cgi?id=118051 Following the suggestion in comment #6, I am filing it here. This computer has a Realtek ALC3263 chipset, which is "dual-mode", i.e., it supports both the HDA standard and the I2S standard. The embedded controller in the notebook uses the ACPI _REV value provided by the OS you use to determine which mode the sound chipset should be initialized in at boot. Up until kernel 4.3, Fedora and Arch were conservative and selected HDA. Starting with kernel 4.4, they moved to I2S and sound stopped working on all Dell XPS 13 9343 machines. The computer's Arch wiki page https://wiki.archlinux.org/index.php/Dell_XPS_13_(2015) claims that kernel 4.5.2 fixed the issue. It seems, however, that it fixed the problem for some 9343 machines but not for others. See, for instance, https://bugs.archlinux.org/task/47989 The notebook is sold with different configurations. My machine is cribari@darwin4 ~ $ dmesg | grep "XPS 13" [ 0.000000] DMI: Dell Inc. XPS 13 9343/0310JH, BIOS A07 11/11/2015 i.e., the 9343 model with Intel i7, touchscreen, 3200 x 1800 screen resolution, Broadcom wireless. According to this comment (https://bugs.archlinux.org/task/47989#comment149467) we can close this bug. Further, it has not been updated for 8 months. |
