[PATCH 3.18 101/178] ALSA: hda/realtek - Fix the regression by widget power-saving

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Takashi Iwai <tiwai@xxxxxxx>

[ 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().
