You want to use --with-debug=full.  detect only enables debug code in
ALSA's card detection.



i think the configure help should be changed; what would you conclude from this list:

 --with-debug=level      give the debug level (none,basic,full,detect)

to me, this certainly implies detect>full>basic>none

Not sure - can you state the exact problem you are trying to solve?


there are two issues:

1. attempting to write to registers that are documented to be read-write doesnt
   result in a change of value; how do i debug this?

2. i have an msi motherboard with a via8237Rplus and a vt1618 8ch codec. it has only
   three plugs on the back that default to a stereo out, line in and mic in.

   they are supposed to be 'Universal Audio Jacks' and thus reconfigurable in the manner   
   mentioned in the documentation that i listed previously - i wont really know if i have this 
   write until i get the write to work
