You can type "cat /proc/asound/card0/codec#* > codec.txt" for each state, changing the name of "codec.txt" each time. When you make a change in alsamixer (or any other audio mixer), the change will be reflected here.

How can I change the jack retasking with the Intel HDA drivers or get further insight into this problem?
First, show the contents of /proc/asound/card0/codec#* files...
Firstly, thank you for replying; the only related cases I've been able to find on the internet suggest to use the 'model=vaio' option to the snd-hda-intel module, but this does not help.
Try the patch below, choose "Line" as the capture source (if you want a mic-input jack -- for the built-in mic, chooes "Mic"), and raise the newly added "Capture Boost" volume.
Firstly, thank you for your time and help.
I have discovered the bug preventing me using the external mic socket before: in the mixer, the user has to select the [internal] mic input, then re-select the line-in (actually external mic) input; reading from (eg) /dev/dsp while changing this, the output suddenly is as expected when the line-in is re-selected.
Since we've got started, where should I look for the 'before' and 'after' state to compare to see into this?
This behaviour is reproducible with both 2.6.20 and 2.6.22-rc7.
Many thanks! Daniel
