[Ricardo Salveti <rsalveti@xxxxxxxxxxxx>]

Tracking down the pa_sink_set_volume call (which is what pactl set-sink-
volume uses), the original sink had the correct real volume, but a wrong
soft_volume (as in my use case the driver/hw is not providing hardware
volume support). The soft_volume was actually at the max volume, which
is the initial value provided by pa_sink_new.

Follows the dbg info from the first call to pa_sink_set_volume call (via
pactl):

Title:
  Volume at login set to Maximum

Status in “pulseaudio” package in Ubuntu:
  Confirmed

Bug description:
  Release: Ubuntu 10.04 64-bit Desktop Edition

  What You Expected to Happen: System volume to remain as set before reboot and as shown in volume panel applet
  What Happened Instead: After reboot/shutdown at and after login system volume is set to maximum

  Extended Description:

  Intel HD Audio Chipset using S/PDIF coax out to speakers and system
  audio set to digital output

  After either rebooting or shutting down my system at the next login
  the system volume will be set to maximum. Once the panel loads I can
  click on the system volume applet and if I move the volume slider in
  any direction the volume will immediately be set to the correct level.

  Here is how the process goes:

  1. (logged in system running)slide volume to 75% using system volume applet on panel
  2. reboot
  3. Login,
  4. login soundbite plays at 100% volume
  5. open rhythmbox play audio track system volume at 100%
  6. click on system volume panel applet, do not click slider, slider shows volume set at 75% as before reboot <---- This is the odd part
  7. click on volume slider and adjust in either direction system volume abruptly adjusts to match the volume level indicated by the slider.

  If any more information is needed please let me know. Thank you

  **MORE INFO 6/25/10**

  This also affects the system alert volume in the same fashion as
  above. Adjusting the slider for the alert value via the panel applet
  reset the volume to the correct level.
