# 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?
