I just got a 1/8" - 1/8" trs cable to connect the headphone out of my px130 to the line in of my sound card and I get HORRIBLE sound. First there is a ton of noise in the background, and it clips with only moderate playing.
I know there is an easy way to record, what am I doing wrong? I wanted to see if it was the piano or my sound card, so I hit record in audacity, saw the huge noise floor, unplugged the cable from the piano and the noise disappeared. The sound is perfect when I play with headphones as well!
Any ideas???

It might be the cable is shorting out in either the jack on the piano or the Line In on the computer. Check to make sure there is no undue weight on either end of the connection. You might have the volume turned up too loud on the piano. Try turning it down near minimum. Another possibility is there is an impedience mismatch between the headphone out and Line In on the computer.

Nope. A short would cause a no-sound problem, not a too-loud/distorted/clipping problem.
And impedance mismatch is inevitable ... and beneficial here since it will reduce the signal level.
The problem is most likely because of the volume setting on the piano. Have you turned it down ... way down?

I just tried turning it way down and that fixed the clipping problem, but the noise floor was LOUDER that the piano sound when I normalized it. When its just sitting there without playing, the input level meter in audacity (the 2 bars that move to show the line level at the top of the program) are at 50% and are red. WTF!?!?!?
I wonder if this is just due to my crappy sound card??? I cant imagine that would be the case though..

Any ideas??? Several things are all working against you. 1) The headphone jack is designed to drive headphones. It is not a line-out jack. I could talk about "impedance" but the answer is just to turn it down low 2) You line -in might also be a microphone input. On some somputers it si switch able. Set it to "line" if you can. you might be able to adjust the sensitivity or "gain" of the input, You have to adjust this to match the volume level of the headphone jack 3) Most PCs have a poor quality built-in sound interface. Yours could be one of those. What you really need is a "studio quality" Firewire or USB audio interface. These start at about $. Don't bother with one marketed to video game players or home theater. Any of the name brands like Presonus, Lexicon, EMU,.. are good. Some of these have built-in MIDI. Get that if you can. All of the "good" audio boxes have 1/4" phone jacks so yu will need a cable to split the PX130 staero jack into two 1/4" mono. If you can't record audio you can always record MIDI and play a software instrument on the computer. There would thn be no analog link and the quality can be very good EDIT: You say it works now? That is one reason why you don't find those little 1/8th inch trs stereo jacks of pro-grade equipment, they are unreliable

I unplugged it from the piano, and actually plugged it into the headphone jack of the pc and recoded some audio from my pc to hear the quality. It was perfect. I put it back in the piano and it sounded much better, not perfect, but the noise was much less noticable. Im confused. Also, my pc sound card has separate mic and line in. The line in seems to be a true stereo line in from the sound control panel..

Doubt its the cable as the signal was perfect when plugged into the headphone jack of my pc speakers. Its definitely not the headphone jack of the piano because it sounds perfect with headphones plugged in.

So for those of you who have a Privia PX-xxx and record in the method I do (stereo TRS cable from headphone jack of piano to line in of computer through audacity or some other recording program), what are your results? Do you use an upgraded sound card? Do you have slight noise in the background when you record? Do you have to keep the piano volume very low when recording to avoid clipping?
Please chime in, Im still looking for answers. Mine sounds OK, but I have to record with the volume very low and I still have a slight amount of background noise.

Its definitely not the headphone jack of the piano because it sounds perfect with headphones plugged in. The problem is with the quality of the PC's built-in sound system. For one, I bet it lacks an analog gain control knob so you have no way to set the sound card's input level. Also there is a mis-match in the sensitivity of the headphone jack and the sound card's input such that you have to turn the piano's volume dow so low that noise begins to dominate. Might be interesting to place a "say" 100 ohm resistor across the headphone jack so that you can crank up the volume on the piano. But you'd also gain a lot with a better quality audio interface. You want a 24-bit interface.
