Audio Code For Linux 4.2 Has Skylake Attention & Other Improvements
Written by Michael Larabel in Hardware on 25 June 2015 at 11:28 AM EDT. 3 Comments
Linux 4.2 has many audio/sound related improvements, including support for newer hardware.

SUSE's Takashi Iwai sent in the sound updates today for the Linux 4.2 merge window. Iwai cited this work as "a busy development cycle at this time, as you can see a wide range of changes in diffstat. There are no big changes but many refactoring and improvements."

In digging through the changes, there's initial support for Intel Skylake audio in HDA core, i965 graphics power well management for Skylake and other new hardware, runtime power management is enabled by default for Intel HDMI/DisplayPort codecs, and a lot of code refactoring. The ALSA HDA/HDMI code also has support for NVIDIA's Tegra30, Tegra114, and Tegra210 hardware. As usual, various quirks were added for improving the Linux hardware support on different devices.

The full listing on sound changes for Linux 4.2 can be found via the pull request.
