Thanks, applied now.
Just wonder, though, whether rather setting
spec->gen.power_down_unused = 1 works. When it's set, the generic
parser applies the own power filter, and it doesn't have the EAPD
check either (plus it does more aggressive power-down of unused
widgets).
Or, maybe we just drop the EAPD check, and move it to specific fixup.
AFAIK, it was required only for old Gateway laptops.

Title:
[Thinkpad R61i/T61] Lenovo sound chip Conexant CX20549 Venice doesn't
work correctly.
Status in “alsa-driver” package in Ubuntu:
Incomplete
Bug description:
Computer: IBM Lenovo Thinkpad R61i
Card: HDA Intel
Sound chip: Conexant CX20549 (Venice)
Device: 00:1b.0 Audio device [0403]: Intel Corporation 82801H (ICH8 Family)
HD Audio Controller [8086:284b] (rev 03)
Subsystem: Lenovo ThinkPad T61 [17aa:20ac]
System: Ubuntu Oneiric 11.10 (desktop-i386)
Kernel: 3.0.0-12-generic-pae#20-Ubuntu SMP Fri Oct 7 16:37:17 UTC 2011
Problems:
1) Integrated microphone doesn't work at all because the driver uses node
0x14 instead of 0x15 for integrated mic and node 0x12 instead of 0x14 for
external mic.
2) Sound output is muted in the "0% <-> unamplified" part of the volume
slider and is working in the "unamplified <-> 100% ->" part only; the driver
doesn't allow amplified part because sound is distorted over 0dB of the PCM
level so there is no need amplified part of the volume slider.
Solution: Attached patch is fixing nodes of integrated and external
microphone and is removing the amplified part of the volume slider.
