Exclamation Sound skips on Dell Latitude CPi A366XT!


Audio output on my Dell Latitude CPi A366XT is constantly skipping on and off while playing sound - evenly spaced every time. (It almost sounds like a cool guitar effect ).

Any idea why this would be?

My soundcard is: Neomagic Corporation NM220 [MagicGraph 256AV] (rev 20)

update:

The sound problem has now changed from skips to repeated clicks at the same intervals. BUT THIS IS ONLY WHILE A SONG IS PLAYING. When i start to play an mp3, it plays the song with loud repeating clicks over top of it. brutal on the ears.

Another thing to note - when i plug in the headphones to the headphone jack... it almost seems like the computer's internal sounds are MIC'd. like, i can hear the cpu click, stuff moving around, and when i tap around the keyboard/base, i can hear that as though it is amplified (especially near the far left corner of the keyboard, near the power button).

I will run further tests and see if this problem recurs using different programs... I'm also trying to install OSS.

ANY HELP OR IDEAS ARE APPRECIATED - i need to get this computer working for recording asap!

I ditched the idea of installing OSS because it wouldn't compile anyway.

Lucky for me I did that. ALSA works great actually. It turns out my problem is entirely with MP3s. I played a WAV file and it plays clear as day, beautiful.

I would like to fix the fact that MP3s skip though. Anyone know what would be causing that?


Also, I have another problem. I'm trying to record sound on this lappy as well - really important i get that working. I wired something to the line-in jack, and hit play, and the computer monitors it automatically. The sound it plays back out to me is beautiful, just as nice as it is coming in.

The problem is, when I use the program "mhWaveEdit" to record this incoming sound to a file, it records along with really clicky static that's much louder than the incoming sound, and VERY awful to listen to. It may be the fault of the program, which is why I'm trying to install audacity (not working, but that's a different thread). In any case, can anyone provide any help?

is there another sound recorder for zenwalk linux i should be trying?

THANKS A LOT FOR ANY HELP I REALLLLLLY NEED TO GET THIS WORKING!!!!


P.S. the thing i mentioned before where the computer was mic'd was true. the internal mic was clearly active, and it was listening and monitoring out through the headphone jack. weird eh?

Exclamation Sorry for the quadruple posts

I've discovered a program called "sox" which is a command-line audio recorder. I used it to record the line-in to a .aiff file. Bad quality - repeating screeching sounds every quarter-second or so.... (very similar to the crap that plays when I play an MP3).

But then I tried recording a .wav file. crystal clear quality - only I realized that the MIC input jack i was using only has Mono sound. So I tried the Line-In input jack, and testing with the computer's monitoring output I heard clearly the other half of the sound - so it was defz stereo.

The problem is now I can't get Sox to record the Line-in jack as opposed to the MIC jack. i'm sure i'll figure it out fairly soon.


However, that doesn't really solve these problems:

1) screeching sounds when playing MP3s in totem/exaile
2) similar screeching sounds when recording .aiff in Sox
3) weird loud clicking sounds (similar to static) when recording WAV in mhWaveEdit. (here's an example: http://teagan.nearthemark.ca/climate...sharkstest.wav )


Helllp meeeee please!
