Hi Niki,
Earlier this day I started a thread about Skype not working with outgoing sound. Now I wonder if it's not a problem with my soundcard. I had a vague suspicion about this, but since it's way off the original topic, I decided to start a new thread about this.
Here's what the soundcard looks like:
[root@grossebertha etc]# lspci | grep -i audio 00:1b.0 Audio device: Intel Corporation 82801G (ICH7 Family) High Definition Audio Controller (rev 01)
the problem seems to be familiar with this chipset, independent from the Linux distribution: - http://www.linuxquestions.org/questions/linux-hardware-18/ich-7-hda-intel-63... - https://help.ubuntu.com/community/HdaIntelSoundHowto
On the other hand, when I try to record sound over the soundcard, the result is quite fuzzy, full of distortions. I tried to fiddle with alsamixer to get rid of the distortions, but to no avail. Here's what I did to record sound over the mic:

Now in the past I configured a laptop with an ICH sound card on it, a small ASUS. I spent like whole afternoons googling and searching through forums, until some day I stumbled over the solution. I had to add something to /etc/modprobe.conf, something like:
alias snd-card-0 snd-hda-intel options snd-hda-intel model=3stack
It could be as easy as 'options snd-hda-intel model=lenovo' (see Ubuntu link) or similar, see http://fedoraproject.org/wiki/KernelHdaDriverOptions.
Searching for "centos intel high definition sound" doesn't show much.
s/centos/fedora, good luck.
