No audio input with Mic, FC7+ALSA

I've messed with Linux in a server setting for FTP, HTML, and gaming servers but I haven't made the switch on my gaming PC until now. That said, I'm having problems getting my mic to work. I'm using the CA0106 card for audio, and with the same hardware configuration it works flawlessly in Windows.

I've toyed with settings to no avail, and tested with Skype and KRec.

Code:

$ cat /proc/asound/cards

 0 [CA0106        ]: CA0106 - CA0106

                      Live! 7.1 24bit [SB0410] at 0xaf00 irq 21

 1 [NVidia        ]: HDA-Intel - HDA NVidia

                      HDA NVidia at 0xfe024000 irq 17

Code:

$ cat /proc/asound/version

Advanced Linux Sound Architecture Driver Version 1.0.14 (Thu May 31 09:03:25 2007 UTC).

Since I don't recall the command to output my settings in text format, I've included a SS of my alsamixer settings here. The only non-viewed setting here is Shared Mic/Line In which is currently set to Line In.

Since the image is small and difficult to view, my settings are listed here.

Code:

Card: CA0106

Chip:

View: [All]



Line in: 100

Mic: 100

Phone: 100



IEC958: Unmuted (I found this actually controls muting for Analog too.)

IEC958 C: 0

IEC958 F: 0

IEC958 R: 0

IEC958 U: 0

Aux: 100

Analog C: 71

Analog F: 71

Analog R: 71

Analog S: 71

Analog S: Line in

CAPTURE: 100

Digital: SRC out

Shared Mic/Line in: Line in

I have attempted to adjust all of these settings. The "IEC*" are for digital output, and I'm using Analog so that's why those are 0. If they are not muted, sound cuts out because my card does not support both analog and digital output simultaneously. Also, The only setting that makes a difference in my audio playback is "Analog F", the rest can be set to 0 and I can hear properly.

I tried to cover all information required to bug this problem, if I've forgotten anything please just throw it out and I'll get you the info.

lets look at the output of the command "amixer"

That's the command I couldn't recall earlier. Here's the output below.

man i reply just to give you a bump to the top.
your sound card is very different from mine.
anybody with a sound card like this can help this guy ?

Thanks for the bump Dogg, I always feel dirty bumping my own posts. :)

I still haven't found a solution to this after tinkering for the past few days, I'd really love some help. I do a lot that requires skype and vent and it's a burden to have a laptop sitting there with Windows just to get it done.

Shameless bump. I have tried searching the internet for hours without results. It's unfortunate but I have to consider reinstalling Crapdows because of this. Any help would be highly appreciated.
