Thanks. Erm, the patch is utterly broken. I fixed manually like below. Please confirm that it's the right fix. Takashi === From: Kailang Yang Subject: [PATCH] ALSA: hda/realtek - Support low power consumption for ALC295 Enter to close more power control widgets at suspend. Remove hp_pin check. Add the default pin 0x21 as headphone. Supported low power consumption, it must do depop procedure when headset jack was plugged or unplugged. So, alc225_init() and alc225_shutup() must run delay when headset jack was plugged or unplugged. If depop procedure not run with delay, it will have a chance to let power consumption raise high.
