Hi Christopher:

OK, I have some additional information.

1.  I finally figured out a way to kill the Radeon HDMI audio:

echo 1 > /sys/bus/pci/devices/0000:02:00.1/remove

If I do this after I log into Ubuntu, the Radeon HDMI option is gone,
and won't return until I reboot.

The other audio devices -- e.g., the analog headphone jack -- continues
to work just fine.

However, I have not been able to figure out how to kill this HDMI audio
device early in the boot sequence, so that the HDMI audio is *never*
enabled.

Unfortunately, trying to do the same thing with PCI 02:00.0 device --
i.e., the Radeon "DIS" discrete graphics card -- doesn't work; I have
to reboot the entire system.

2.  The latest (vmlinuz-4.3.0-040300) works the same as the 15.10 kernel;
no better, no worse -- at least as far as the Radeon graphics is concerned.

Symptoms: the Radeon discrete graphics unit (DIS) unit keeps turning off
and on every 5 seconds or so.  I used to think that it was the HDMI audio
that was somehow triggering this, but now that I learned how to turn the
HDMI audio off (see above), I can see that this is not the case.

3.  There may be some interaction with the VLC video player.  Even though
I've told VLC to not use any hardware (i.e., GPU) acceleration, VLC may
still be trying to turn on the DIS discrete graphics unit.  I haven't
been able to find any documentation about how to keep VLC from trying to
turn on the DIS graphics unit.

I'm open to other suggestions about how to keep the DIS unit turned off.

BTW, for some reason, the older (non-DPM) mode for this Radeon graphics
unit no longer works correctly.

The following command:

cat /sys/kernel/debug/vgaswitcheroo/switch

tells me that the power state of DIS is "DynOff", even when I boot the
machine with radeon.dpm=0.  It shouldn't say "DynOff"; it should simply
say "Off".

4.  I did notice one small change from the previous kernel.  I have
"xsensors" installed, which reports the temperature of the Radeo
graphics unit.  In the latest 4.3.0-040300 kernel, when the DIS is
"DynOff", the temperature is reported as "0 degrees C".  It now
reports the temperature only when DIS is on -- e.g., "DynPwr".
