# X230 reported the sound card as: 00:1b.0 Audio device: Intel Corporation 7 Series/C210 Series Chipset Family High Definition Audio Controller (rev 04) == HDA Intel PCH, ALC269VC Analog
# X240 reported the sound card as: 00:1b.0 Audio device: Intel Corporation Lynx Point-LP HD Audio Controller (rev 04) == HDA Intel PCH, ALC292 Analog
Now I managed to make suspend-to-ram work by using sound as module instead of build-in.
Here's the difference ...
# bad CONFIG_SND_HDA_CODEC_HDMI =y CONFIG_SND_HDA_INTEL=y CONFIG_SND_HDA_INPUT_BEEP=y CONFIG_SND_HDA_CODEC_HDMI=y CONFIG_SND_HDA_GENERIC=y
# good CONFIG_SND_HDA_CODEC_HDMI =m CONFIG_SND_HDA_INTEL=m CONFIG_SND_HDA_INPUT_BEEP=m CONFIG_SND_HDA_CODEC_HDMI=m CONFIG_SND_HDA_GENERIC=m
Strange?
