No HDMI audio, with Mint 17.2 64-bit MATE, and Z3735F Compute Stick?

[VirtualLarry]

Trying to figure this out.

Hardware is a MeegoPad T02 Ubuntu Edition.

Mint 17.2 64-bit MATE installed, after copying bootia32.efi to /EFI/BOOT , then running a shell script to install 32-bit GRUB2 after installation.

Things I've tried:
Upgrading the Kernel, from 3.16.0-38, to 3.16.7-031607-generic

Deleting / resetting my PulseAudio configuration, and logging out and back in.

Edit: output of "sudo lspci"

00:00.0 Host bridge: Intel Corporation ValleyView SSA-CUnit (rev 0f)
00:02.0 VGA compatible controller: Intel Corporation ValleyView Gen7 (rev 0f)
00:14.0 USB controller: Intel Corporation ValleyView USB xHCI Host Controller (rev 0f)
00:1a.0 Encryption controller: Intel Corporation ValleyView SEC (rev 0f)
00:1f.0 ISA bridge: Intel Corporation ValleyView Power Control Unit (rev 0f)

Edit: I got my info on how to install Mint 64-bit onto the Compute Stick here:

I ran the two scripts that he provides, one for z3735f, and one for dsdt (whatever that is), rebooting in-between.

I now have an audio device labeled "IntelHDMI" in the PulseAudio control panel in MATE, but it only shows "Analog Stereo" and "Off". And when I start up a streaming radio station in Firefox, I can hear really short bursts of audio, if I also scroll or view pages. Like, some audio is slipping through the HDMI port, when I do some sort of graphics operation.

When I click on "Test Speakers", I can get a brief crackle, and that's it.

Now when I do an "aplay -l", I get this:

**** List of PLAYBACK Hardware Devices ****
card 0: IntelHDMI [IntelHDMI], device 0: IntelHDMI [IntelHDMI]
  Subdevices: 0/1
  Subdevice #0: subdevice #0

Edit: Added this PPA:
https://launchpad.net/~ubuntu-audio-dev/+archive/ubuntu/pulse-testing
and did "sudo apt-get install pulseaudio", then rebooted.
Then I didn't have a speaker icon to control my audio anymore. When the update icon came up, it said I had a level3 update for "Pulse Audio", so I installed it, rebooted, and got my icon back. Still no continuous sound.

Edit: Now I'm having issues with Linux Mint rebooting while on Skype. The weird thing is, it's an orderly shutdown and restart, not a forced power-off. So I don't know if it's overtemp, or something with the power button or associated circuitry.

When I booted Linux Mint, not on Skype, and then selected Shut Down, it shuts down, then it powers on again. So I forced a shutdown by holding down the power button for 4 seconds, and it shut off... then it powered back on again! So it seems like hardware problems with this unit, maybe?

Have you tried perusing the alsa mailing lists? There have been issues with the audio firmware and the Atom Z3735F.
