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:
http://wiki.ekiga.org/index.php/Troubleshooting#Audio_problems
http://wiki.ekiga.org/index.php/Audio_setup
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 :-)
