Yes, it is still unimplemented. So, it's expected not to be there
yet. If you can hack it by yourself, let me know.

the problem, and it's hard to debug without a hardware. Could you try
to figure out which setup is missing?

Strange, the jack mode should appear all input jacks except for the
fixed pin. Could you give alsa-info.sh output with the latest code?
