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.

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...
