    There are three types of lies: lies, d@mn lies, and claims of superior audio quality.

    Have your amps got gain controls?.if so wind them down.
    are you using compressed audio files wma,mp3 etc as low sample rates will cause a loss of quality
    are your speakers up to the job?.can they cope with the amp output?.over drive them and muffled distortion is going to happen

    I'm using motherboard sound chip with 4ch amp with 12 speakers and a seperate 12" sub with own amp and it sound great.sound control is done through centrafuse and is totally controllable

    Two amps and both are Memphis. One is a 4 channel 75w and the other is 1 channel 1100w into the sub. The amps are literally turned all the way down.

    When turning up the volume on the carputer 25-30% its about as loud as you would expect at 90-95%. Accidentally clicking the volume slider up while hitting the volume up button results in an audio explosion that sends jolts through your intestines and makes you excrement on yourself.

    Either you turned your gain knobs on your amp turned the wrong way and they are maxed out or you have some gain in the software player maybe the EQ gain in winamp? Try another software player to check. I suspect your amp gains first as stated previously though, even if you THINK you have it set correctly check it again anyway. Third maybe see if anyone is reporting problems with the drivers. Sometimes you might have to go to realtek to get better drivers instead of what is supplied with the mobo.

    Im currently using the intel the blkdg45fc motherboard on windows xp and a programm called idt audio.This setup allows for 5.1.Im not using a centre channel but with the audio programm gives me the ability to adjust each individual speaker level and time alignment with i think 10 band eq. Sound quality was a massive imporvement being able to choose each speakers hpf or lpf settings.The only problem I encountered was the preout voltage that was below 2v.I solved this buy using 3 simple rca line drivers to my amps and then was able to turn the amp gains down and fine tune the speakers.This solved all my issues.Centrafuse control the graduall volume with no sound spikes..engines noise etc.Its sound quality by far surpasses what my alpine 505 produced before switching to my car pc and for less money.Hope that helps.

    also, everyone who has onboard audio needs to select the bitrate setting in the audio config. by default, its set to 16bit 44khz or worse, and i think thats why a lot of people get bad impressions. the newest onboard solutions can crank up to 24bit, 192khz and once you do that a whole other world of sound comes out.

    ooo yes, one reason i love the xonar's. i've had a carpc for a bit over a year, everyone who's seen and heard the audio is wowed. i'm considering getting a line driver for it here soon though.

    Best to use an oscilloscope to measure the output and distortion from your carpc.

    I have a pioneer deck along with a carpc. Using a 1khz test tone and the volume at max the pioneer was around 7v max. When using the same test tone on the pc (which runs through the pioneer aux) I saw a 9v max. So even though I didn't see any distortion I turned down my volume slightly on the pc so both sources would play at the same levels.

    I think this would help you see what type of distortion etc that is giving you so many problems.

    i cant remember what the ratings are of my subs... but i do know they have never needed to be turned over 60% and when i leave them on 60% it allows me to have a nice volume range straight from the pc. This way they are not being over driven and this has been the case with a few installs that i have tested people's equipment on.

    With virtually all types of setup, You should be able to balance a nice range of the volume control on your pc to give you 1% barely audio if your ear is at the speaker to 100% with it at the limits of your speakers.

    Also in your case perhaps your might want to balance your pc audio out by lowering your WAV slider.
