First let's try cleaning up the alsa.conf file. Try something like this.

Code:
alias snd-card-0 snd-hda-intel
alias sound-slot-0 snd-hda-intel
options snd-hda-intel model=toshiba-s06
See if that gets it going. If not, try some of the other options from the HD-Audio-Models.txt file.

Good luck. ;-)

I tried your suggestion and discovered that: when I scream near mic hole, Skype play back to me with a light voice.

Have you raised the mixer levels for the mic? Is there a "mic boost" or "amplifier" option for the mic? Do you have multiple options for the mic, I.E. Mic 1, Mic 2, Digital Mic, etc.?

Good luck. ;-)

You can see it from amixer output:
Code:
Simple mixer control 'Mic',0
  Capabilities: pvolume pswitch
  Playback channels: Front Left - Front Right
  Limits: Playback 0 - 31
  Mono:
  Front Left: Playback 30 [97%] [10.50dB] [on]

Simple mixer control 'Digital',0
  Capabilities: cvolume
  Capture channels: Front Left - Front Right
  Limits: Capture 0 - 120
  Front Left: Capture 120 [100%] [30.00dB]
  Front Right: Capture 120 [100%] [30.00dB]
Simple mixer control 'Input Source',0
  Capabilities: cenum
  Items: 'Int DMic' 'Mic'
  Item0: 'Int DMic'
I have re-compiled alsa driver from source code on the realtek.com.tw, and now the amixer output like below:
Code:
Simple mixer control 'Master',0
  Capabilities: pvolume pswitch pswitch-joined
  Playback channels: Front Left - Front Right
  Limits: Playback 0 - 31
  Mono:
  Front Left: Playback 19 [61%] [-18.00dB] [on]

  Limits: Capture 0 - 31
  Front Left: Capture 31 [100%] [34.50dB] [on]
  Front Right: Capture 31 [100%] [34.50dB] [on]
Simple mixer control 'Capture',2
  Capabilities: cvolume cswitch

  Capabilities: pvolume pswitch
  Playback channels: Front Left - Front Right
  Limits: Playback 0 - 31
  Mono:
  Front Left: Playback 31 [100%] [12.00dB] [on]
  Front Right: Playback 31 [100%] [12.00dB] [on]
Simple mixer control 'Digital',0
  Capabilities: cvolume
  Capture channels: Front Left - Front Right
  Limits: Capture 0 - 120
  Front Left: Capture 120 [100%] [30.00dB]
  Front Right: Capture 120 [100%] [30.00dB]
Simple mixer control 'Input Source',0
  Capabilities: cenum
  Items: 'Mic' 'Front Mic' 'Line' 'CD'
  Item0: 'Front Mic'
Simple mixer control 'Input Source',1
  Capabilities: cenum
  Items: 'Mic' 'Front Mic' 'Line' 'CD'
  Item0: 'Front Mic'
Simple mixer control 'Input Source',2
  Capabilities: cenum
  Items: 'Mic' 'Front Mic' 'Line' 'CD'
  Item0: 'Front Mic'
As you can see: there are 3 Input Source channels which are adjusted to Front Mic.

And... it still didn't work.

Thanks for your enthusiasm.

Have you tried alsamixer instead of amixer? It will give you a graphical look at all of the channels. Have you tried the "Mic" option in place of the "Front Mic" option? If not, give that a whirl as well. With the HDA cards, not all channels are always correctly identified.

Aside from that you could try the HDA Analyzer.

Good luck. ;-)

Yes, obviously. I always adjust by alsamixer but give amixer output to you.

I have tried and only hear the fingers knock with Front Mic and Mic, Line and CD has no.

Thank about HDA Analyzer. After Googling, I tried to change VREF from 80 to GRD or 50 in node 0x18, but no luck:
Code:
Node 0x18 [Pin Complex] wcaps 0x40018f: Stereo Amp-In Amp-Out
  Amp-In caps: ofs=0x00, nsteps=0x03, stepsize=0x27, mute=0
  Amp-In vals: [0x00 0x00]
  Amp-Out caps: ofs=0x00, nsteps=0x00, stepsize=0x00, mute=1
  Amp-Out vals: [0x80 0x80]
  Pincap 0x0000173e: IN OUT HP Detect Trigger
    Vref caps: HIZ 50 GRD 80
  Pin Default 0x04a15020: [Jack] Mic at Ext Right
    Conn = 1/8, Color = Red
    DefAssociation = 0x2, Sequence = 0x0
  Pin-ctls: 0x22: IN VREF_GRD
  Unsolicited: tag=0x00, enabled=0
  Connection: 2
     0x0c* 0x0d

There are a couple of other helpful guides with suggestions here.

Alsa Mic FAQ, Alsa Recording FAQ.

Good luck. ;-)
