Interesting.  Is it with or without model option?  There is a model
option specific for aspire one (acer-aspire).  Doesn't it work better?

For comparing the hardware setting, please you run alsa-info.sh with
--no-upload option, and attach the generated file at each state.  This
shows the real codec register values.

Also, please run the same procedure for acer 5720, too.
