Can you try if applying the attached makes things work as you'd expect with 
respect to the recording levels? Over here it seems to, although I get the 
feeling we might as well rename the control "Distortion Levels" as keeping 
it at 0 is the only sensible thing.

Even if this works, it's not a final fix, just to confirm. Given that you 
posted to alsa-user... if you're not setup to apply this patch (to any semi 
recent source) and recompile the driver I hope someone can help.

With respect to the duplex issue -- there seem to be no docs for 688 and 
1688 which is a bit of a problem.
