Yeah, I think we can add EAPD handling as default for IDT92HD71xx codecs. I've never seen machines that can't live with GPIO0 bit up.
enable_msi doesn't seem to affect the auto-muting problem. I played with every single node in hda-analyzer but can't get auto-mute work. I can manually mute the HP output and the internal speakers by checking/unchecking OUT checkboxes on relevant NIDs. There's a 8xn matrix for GPIO settings, I played with them as well to set unsol but nope.
I want to remember that dell-m4-1 makes automute work but breaks the mixer channels:

Err, I know that I didn't answer the last question in the thread as I'm a little bit lost in the NID pool and didn't have time to investigate further.
Could you check whether this still valid?
Basically the model option doesn't change the auto-mute behavior. It just changes which pin to be detected and which pin to mute. So, if model=dell-m4-1 makes the auto-muting working, it means that the BIOS setup is broken.
I looked through alsa-info output now, and found the culprit. NID 0x0f is set as a line-out, and currently the driver doesn't don't do auto-muting for line-out unless a headphone is present. Changing it to a headphone should fix. Or you can give hp_detect=1 hint via sysfs and reconfigure.
