Can Hear From Mic through Speaker but cant capture in audacity

Hi,

I have the following Sound Card.

05:08.0 Multimedia audio controller: C-Media Electronics Inc CM8738 (rev 10)
        Subsystem: C-Media Electronics Inc CMI8738/C3DX PCI Audio Device
        Flags: bus master, medium devsel, latency 64, IRQ 16
        I/O ports at e800 [size=256]
        Capabilities: [c0] Power Management version 2
        Kernel driver in use: C-Media PCI
        Kernel modules: snd-cmipci

It is detected and I can hear the sound Sound from Mic Through the speaker.
How ever I am not able to record it in audacity.
Mic Does not work on Skype too :-(

Could some one help me trouble shoot this?

thanks :-)

Are other apps able to record from mic? Maybe youve to choose the right device in audacity (but Im convinced that you have...)

Re: Can Hear From Mic through Speaker but cant capture in audacity

I had similar problems and could get nothing whatsoever when trying to record from the microphone or using it in Skype (it was obviously muted completely in some way). Tried everything I could in alsamixer, and installing PulseAudio didn't manage to get it working either.
However I installed gnome-alsamixer, and ticked a few 'Rec.' check boxes and everything works now as it should! Sorry I can't pin down exactly what switched it on.

Re: Can Hear From Mic through Speaker but cant capture in audacity

I don't know how this is done with pretty GUI tools but since you're using ALSA you must have alsamixer (which to the annoyance of many users, does not show capture controls by default). Start it with "alsamixer -V capture" and I'm guessing a lot of captures will be turned off because I keep seeing "Capture [off]" in the output you've posted. Press spacebar to activate them, particularly "Mic" and then it should work.
