I appoligize for not taking a close look at all the info that you 
carefully offered with your question. Hopefully I would be able to offer 
a solution though. I find alsamixer to be pretty confusing. So (of the 
two mixers below) I would suggest using KAMix. It combines all the 
(confused and illogically placed) controls of alsamixer into simple 
controls that make more sense. And I'm not sure if what you're 
experiencing is the same as what I've come across. But it sounds simular...

I also get chorus-like (and echo-like) effects when I'm doing...
ecasound -i:/dev/dsp -o:/dev/dsp
(in from card 1 and directly out to card 1)

I have a soundblaster and this is what I did...

- In KAMix
     - Go to the "Capture" tab
     - Turn off "Activate" under the "Wave Capture" control
      (make sure both are "unchecked")

- In alsamixer
     - (de)activate capture on the "Wave" control
       (Use the left or right keys to move to "Wave",
       then press the space bar and it will toggle
       "CAPTUR" at the top of the "Wave" "level slider"
      (or whatever you call it)

Please let me know if this had any effect. I'm trying to keep track of 
information that was helpful and not so helpful. This way I have an idea 
if it is something that I can offer to other people when the question 
comes up again.
