Linux Audio Is Being Further Modernized With The 4.1 Kernel

Written by Michael Larabel in Hardware on 16 April 2015 at 07:43 AM EDT. 51 Comments

Takashi Iwai sent in his sound driver updates for Linux 4.1, which includes major modernization with the standard bus for ALSA in the sequencer core and HD-audio code.

This sound/audio updates also include the HD-audio code now supporting regmap to replace their in-house register cache code, a split of HD-audio into a core library and "legacy" driver portions, in preparation for the upcoming ASoC HD-audio driver.

The sound update for Linux 4.1 also uses the standard runtime power management code now for codec power savings, improved Dell headset support by HD-audio, Intel platform updates within the ASoC code, support for Google's Storm platform, and various other new codecs are now supported.

More details can be found via the sound pull request.
