Here is a scenario, I have my Poweredge T410 which has no onboard audio.  I
have a Kennsginton USB dock with built in audio, USB, Serial and LPT for added
expansion.  I also have plugged in a set of Logitech speakers that sens power
and audio through USB, then i have a logitech USB headset.

When the system boots up the volume control knob on the keyboard doesn't
manipulate the volume for any of the devices.  The Logitech speakers are set to
be the systems default in Pulse Audio.

Another Scenario,  My Inspiron 3850 has onboard audio and if i boot up just
with that then the volume control buttons on the keyboard function as expected.
 If i boot up with either my Logitech VOID or the Triton Kunai USB headset
plugged in then the keyboard's volume controls don't function for any device
even though the onboard is the main default.
