Hi!
I'm using onboard sound with NVidia CK804 chip with the snd_intel8x0
alsa driver and have the problem that some of my music sounds really
bad when played.
Let me give an example. I have a cd with a song I like. It sounds good
when played directly from the CD via the internal audio connector.
Now I rip the song with cdparanoia to a wav file. When I play this
file it sounds realy bad. I don't know how to describe it but I think
it's some kind of droning. When I play the file using my usb audio
device it's sounds fine.
To a certain extent I have this bad quality with a lot of my music
files. But what I notices is that I have never had this with sound in
a video. Now I wonder if this might be some problem with music having
(normally) 44100 Hz sample rate and video sound 48000 Hz. Is this
possible? Maybe even a known problem?

intel8x0 clocks at 48000hz so you might wan to try the 'plug' plugin.
ex. aplay -f cd -d plughw:0,0 file.wav

Apparently upon the beginning of the barrage, the donkey broke
discipline and panicked, toppling the cart. At that point, the rockets
disconnected from the timer, leaving them strewn around the street.
Tethered to the now toppled cart, the donkey was unable to escape before
the arrival of U.S. troops.

No, this does not change anything. But if the hardware only supports
48000 Hz, I will try to convert the file to that rate before playing
it. Would be interesting to see if this makes a difference.

Sample rate copnversion shouldn't be the problem - the software you're
playing it with should do all this for you.
What it could be is volumes. Admittedly "droning" doesn't sound like
a clipping problem, but what you hear as droning, I might describe
differently.
Anyway, fire up alsamixer and start playing with your master and PCM
volumes. If it doesn't change anything, then at least it's another
thing off the list of possible causes.

You were totally right. It was a mixer problem. I had the PCM set to
its max value. Lowering it somewhat made the bad sound disappear.
Thank's for the hint. By the way, what stage of the sound processing
does the PCM affect? I guess it's aplied to digital values right
before DA conversion. Am I right?

I *think* so. I'm not an expert, so it might be a little more complex
than that.
This is why I don't like XMMS monkeying with it when I change the
volume - everything goes up and down with it.

But doesn't XMMS can change the volume internally, with the option "software
volume control"? At least, when I change the volume in XMMS with that option
activated, nothing else change in my system main volume.
Byez!
