From: Takashi Iwai <tiwai@xxxxxxx> This patch has been added to the 3.18 stable tree. If you have any objections, please let us know. =============== [ Upstream commit cffd39668177afe5566104a2f289242c3c5ce3d1 ] While enabling the widget power-saving for ALC269 & co, the important setup was forgotten -- stream_pm ops. Without this setup, the paths for PCM won't be powered up at all. Also, the power_filter callbacks used in ALC269 & co need to chain to the default snd_hda_gen_path_power_filter().
