I believe a majority of the kernel work is complete, but from some off
kernel mailing list discussions I understand that pulseaudio doesn't
understand the control interface that gets used for I2S for jack
detection. 

There is some work in progress here to standardise the jack kcontrols
between HDA, ASoC and other ALSA drivers. I would expect this to be
upstream in the next week or two.  

 UCM can't be used for it. 

UCM configs and jack support for this DSP and codec combination have now
been upstreamed :)

 This leads to a really confusing mixer design that needs a variety of
toggles manually changed when headphones or a headset get plugged in.

Generic patches to support UCM jack switching are now upstream in
pulseaudio too.

  There have also been some stability problem with audio reported
after a few days usage.

Can you send these to me privately.

Thanks
