It's good to know :)

That means the pin 0x16 is connected to the headphoone output.
Note that ALC880 has no overall playback controls for all channels.
The volume of each stereo channels is controlled independently.
(That's why there is no "Master" control there.)

Does the device have surround and center-lfe outputs?  Are they shared
with line-in and mic-in?
Also, does "Front" volume affect the internal speaker volume?

This is an unknown problem, so far.
We got a similar problem but it was solved by setting TCREG bits 0-2.
Possibly a similar mis-configuration by broken BIOS.
