POOR RECORDING QUALITY
hi everyone, I am an italian guy on his way to linux. I treid a few distributoins before and I always had configuration problems on my laptop (compaq presario 2580us P4 2.3Ghz 512 RAM), before installing mepis. It is by far the best I used. it works just fine without much work, but there's one thing I just can't figure out: the sound recording quality (using audacity) is very poor. My voice comes out very disturbed, a lot of cracking and frying, if you know what I mean. I'm sure it's not my mic since in windows it works ok. playing music is quite ok though, nothing like that usually happens (even though i tried a "sound check" in "OS center" and the sample came out with two evident pauses, which are not supposed to be therem, I guess). I tried playing a bit with the mixer, but it was of no avail.
windows says I have an AC-Link Conexant audio device, and down here there's the result of kudzu -p (I am a newbie, I got it following some forums about audio problems)
class: AUDIO

the soundcard information I found at the "info center":

Thank you very much to everyone that's giving a look to this.

You might be right!
Yes, reording from console is definitely much better than under KDE! I did what you suggested and the quality of my sample file was absolutely acceptable.
Do you think there is a way to fix that keeping KDE? I mean, being a newbie, I love KDE as much as I am intimidated by a shell
thanx a lot bob
Re: You might be right!
I have a Sound and Multimedia in my Kde Control Center, but no Sound Server in it. There is a Sound System, which freezes all of my applications involving sounds if disabled, so I guess it's not what you were talking about
still there
quality was already 16 Bits, I tried the buffer thing as well but my problem is still there. Playing music is ok, sometimes it jumps when I open some application (Skype for xample) and XMMS' commands have about 1-2 seconds delay (maning that if I lower the volume it takes 1-2 seconds to set where I want it, or, say, if I skip to the middle of the song) but that does not bother me too much, since quality is fine. and setting the buffer from top to half the way gave me a better "test sound". What isn't working is the recording: Still too disturbed (using audacity)
IMPORTANT
maybe this is important. I noticed that when Linux is booting it says:
"alsactl restore failed" with message "no state is present for card A5451"
