Hi,
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)
Actually plain sound (output) works OK. I can use XMMS, MPlayer, VLC and the likes without any problem.
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:
$ arecord > ~/test.wav
This actually sounds like you have "EMI Interference" Electro Magnetic Interference getting into your Mic Cable or maybe a bad mic or cable. Try another mic if you have one or reroute the cable for the mic. Could also be your sound card can't process the audio fast enough.
