If you can compile directly from svn it is already great, otherwise if you want to
build the debian package you can just apt-get source virtualbox, enter the directory
and dpkg-buildpackage it to create the binaries.

It is up to you :)

BTW did you try the Debug switch?
Build type:
  -d, --build-debug        build with debugging symbols and assertions

it is listed in configure script.

cheers,

G.

Title:
  [Emulated AD1980 AC97 inside Virualbox 5.0, playback] volume slider
  problem

Status in Virtualbox:
  New
Status in alsa-driver package in Ubuntu:
  Incomplete
Status in virtualbox package in Ubuntu:
  Confirmed

Bug description:
  Volume Slider is only controlling PCM channel and is not controlling
  Master. In effect, Master is restricting the audio level to the
  default of approximately 45 Percent. In order to raise the Master
  Volume Level, alsamixer is capable of changing Master. Without
  manually raising Master to Max Volume, Volume Slider can only control
  volume from 0-45% which is the default level of Master.
