lost sound upgrading to Jessie

[Mark Copper <mlcopper@gmail.com>]

Hi all,

After distribution upgrade to jessie sound no longer works.

If user kills pulseaudio process, these warnings appear in "messages"
log when pulseaudio respawns:

gnome-session: (gnome-settings-daemon:1466): media-keys-plugin-WARNING
**: Unable to get default sink

and

gnome-session: (gnome-settings-daemon:1466): media-keys-plugin-WARNING
**: Unable to get default source

I'm guessing those warnings are near the root cause, but I don't yet
understand the subroutines that trigger the warnings.

Any suggestions how to proceed?

# uname -a
Linux rigel 3.16.0-4-686-pae #1 SMP Debian 3.16.7-ckt25-1 (2016-03-06)
i686 GNU/Linux

# lspci | grep -i audio
00:1b.0 Audio device: Intel Corporation 82801JI (ICH10 Family) HD
Audio Controller

$ ps -e|grep -i audio
  339 ?        00:00:00 hd-audio0
13783 ?        00:00:00 pulseaudio

Thanks for reading.
