Yes, that's also what I have, with the addition of PulseAudio making its 
own party...

I have none set, I use the stock "alsa-base.conf" file with no added 
tweaks but despite I can see several devices when I choose the Intel HDA 
card from alsamixer, I can't make the Mic to goes out from Speakers.

Ekiga provides some tips for configuring the audio:


Anyway, I wouldn't test the mic using Ekiga. I say this because the voice 
quality can be severely affected not just by the application/sound 
configuration/mic but the SIP/VOIP number you're calling because not all 
ISTP provide low jitter and packet loss levels which are vital to obtain 
a crystal clear audio.

Also, note that for these kind of services (Internet calling) is better 
to use a well-engineered and quality headset/device (I'm very happy with 
my Plantronics ".Audio 626 DSP"). There's a highly noticeable 
difference :-)
