Daniel,
Testing under Ubuntu 13.10 allows the use of the internal sub-woofer.
The sub-woofer controls in the Sound settings are still not usable, but
using the slider for Fade from rear to front speakers under the Analog
Surround 4.0 Output mode allows for panning between the two internal
speakers near the monitor and the internal sub-woofer near the front of
the keyboard (towards the user). Using Test Sound also makes it apparent
that the internal sub-woofer is now being recognized as the Rear Left
and Rear Right speakers.
Raymond,
Here are the outputs for the commands you requested that I run:
Command: "sudo hda-verb /dev/snd/hwC0D0 0x3e 0xf00 0x9"
Output: nid = 0x3e, verb = 0xf00, param = 0x9
value = 0x200500
Command: "sudo hda-verb /dev/snd/hwC0D0 0x3e 0xf00 0xe"
Output: nid = 0x3e, verb = 0xf00, param = 0xe
value = 0x1
Command: "sudo hda-verb /dev/snd/hwC0D0 0x3e 0xf02 0x0"
Output: nid = 0x3e, verb = 0xf02, param = 0x0
value = 0x1c
