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.
