Hello Anthony,
This issue still exist even tested with the latest oem-audio-hda-daily-dkms - 0.201411191501~ubuntu14.04.1 from the PPA .

However, I found out that this issue is identical to bug 1383997, the detection works with power source plugged.
And adding the following entry into /etc/modprobe.d/alsa-base.conf could make it work without power source plugged:
"options snd-hda-intel jackpoll_ms=500"

Thanks
