Thanks, Takashi.
I don't know what tools and invocations to use test out the GPIO values you describe. I think you're saying I shouldn't bother toggling things through HDA Analyzer as there's nothing obviously wrong in that part of the configuration (as reported by alsa-info.sh which is attached as requested).
I noticed in HD-Audio.txt a section which mentions a similar problem and IDT codecs specifically (below). Is there an IRC or mailing list where people could talk me through the basics of trying different GPIO/EAPD, Power Enable or Pin Sense manipulations. I wouldn't know how, yet. If I succeed I'll report back.
Hopefully this will be worth it, as I think the N5110 is a pretty popular model with a common card, and probably a bunch of Dell hardware could get fixed if it could be figured out.
You can change the GPIO setup via hda-verb on the fly. For example, to set GPIO bit 0, try hda-verb /dev/snd/hwC0D0 0x01 SET_GPIO_MASK 0x01 hda-verb /dev/snd/hwC0D0 0x01 SET_GPIO_DIR 0x01 hda-verb /dev/snd/hwC0D0 0x01 SET_GPIO_DATA 0x01 where the output direction is assumed, and only GPIO 0 is set. For GPIO bit 1, hda-verb /dev/snd/hwC0D0 0x01 SET_GPIO_MASK 0x02 hda-verb /dev/snd/hwC0D0 0x01 SET_GPIO_DIR 0x02 hda-verb /dev/snd/hwC0D0 0x01 SET_GPIO_DATA 0x02 and 0x04 for GPIO bit 2. Your device have up to three GPIO bits.
If none of above doesn't any change, try to set DATA 0 instead of 1, and/or DIR 0 instead of 1.

QUOTING FROM HD-Audio.txt >>>>>>>
If you are masochistic enough to debug the driver problem, note the following:
- The speaker (and the headphone, too) output often requires the
external amplifier. This can be set usually via EAPD verb or a certain GPIO. If the codec pin supports EAPD, you have a better chance via SET_EAPD_BTL verb (0x70c). On others, GPIO pin (mostly it's either GPIO0 or GPIO1) may turn on/off EAPD.
- Some Realtek codecs require special vendor-specific coefficients to
turn on the amplifier. See patch_realtek.c.
- IDT codecs may have extra power-enable/disable controls on each
analog pin. See patch_sigmatel.c.
- Very rare but some devices don't accept the pin-detection verb until
triggered. Issuing GET_PIN_SENSE verb (0xf09) may result in the codec-communication stall. Some examples are found in patch_realtek.c.

In case anything has changed in my config since the original info run, here is the same script run right now...

Could you rather attach? Then it'll be archived and searchable.
Anyway, I don't see any obvious problem in the output. If the pin assignment is correct, the routing and amp setups should be OK with the current status.
Maybe it's a missing GPIO setup. Try to adjust GPIO mask, direction and value bits.

I have tried the attached script, which hopefully corresponds with the GPIO exploration regime you wanted me to try. Please take a look at the sequence in case there could be some combination I missed based on trying to interpret your description, or if there's some kind of reload step I need to do.
Yeah, there are some bugs :) The combination should be (mask/dir/data) 1/1/0 1/1/1 1/0/0 1/0/1 2/2/0 2/2/2 2/0/0 2/0/2 4/4/0 4/4/4 4/0/0 4/0/4
Also, as a test, use aplay with -Dplughw option. This skips PA and others.

When running this GPIO script as... sudo ./setgpio.sh ...with headphones on my N5110 it plays the sample every time, and with speakers it is always silent.
Here's an example log of execution...
