Please plug in the headphone, then run alsa-info.sh and upload the alsa-info.txt

BTW, what do you mean "Sound works for a while, then breaks"?

Sorry for the poor description.

Basically, if my headphones are not plugged pre-boot I cannot get them to register (I think I got them to work post boot by reinstalling pulseaudio and trashing the config but not am not certain).

Here is the alsa-info.txt when they are plugged in pre-boot:

Here is the alsa-info.txt when they are NOT plugged in pre-boot and do not show up in the settings:

Logging in and out works. So I imagine the headphones just need to be plugged in pre login.

Here is a diff working vs non-working:

Weird, even you plug the headphone before booting, the headphone is still not recognized. I don't know why your headphone could work in this situation.

this is from #3:
 control.11 {
  iface MIXER
  name 'Headphone Playback Switch'
  value.0 false
  value.1 false
  comment {
   access 'read write'
   type BOOLEAN
   count 2
  }
 }

So, maybe the front headphone jack routes to usb sound card?
