(Get the code!)
I have a similar problem and found that switching to 7.1 (8 speaker) fixed it. Basically I did the following:
1) Naively plugged in the three stereo cables according the the color coding on the speaker cables (Logitech X-540) and motherboard (Asus M4A785T-M/CSM). Configured system to 5.1 analog, this resulted in whining and poor volume "loudness".
2) Thoroughly compared Logitech's color coding of the speaker cables to my motherboards, found an issue there which was not clear from Asus's documentation to be an issue, but switched plugs around leaving on 5.1 analog, had same problem!
3) Went back to original configuration, switched to 7.1 analog, no problems, great volume and sound quality.
In the end I am not sure if this is a problem with the motherboard's sound outputs being indicated incorrectly and possibly specified incorrectly (wqhich is why I have to use 7.1 and not 5.1, I only have 6 speakers). I am really not sure if this is a bug in Ubuntu or the motherboard embedded sound card (VIA VT1708S).
