Thanks for testing.

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

Hm, this is really mysterious.  I have no idea which init code causes
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?
