Soundcard line input too loud on capture

[brucebertrand]

Hi all,

I have an nVidia CK804 based integrated soundcard and am having problems with the line input.
When I un-mute the line-in and listen, it sounds fine. But when I try to capture audio through it, the level is way too high and results in lots of clipping. However, the sound that gets passed through to the speakers stays fine, its just the captured audio that is distorted.

I realize that integrated sound devices are usually pretty bad, but this seems very abnormal.

This card uses the intel8x0 ALSA module.

Anyone have a clue as to what's going on?

Just a guess:
What are you capturing it with? As inputs are typically low amplitude, sometimes the recording program boosts the sound by default. (and in this case that might be causing the clipping).

I've actually never encountered an audio capture program that does that.
For the record, I get the same results in arecord, Audacity, mhwaveedit, and various Jack based apps.

I believe its either a driver problem (perhaps a quirk in this hardware that the intel8x0 module doesn't recognize), or simply a hardware problem.
