Public bug reported:
I have speakers built into my monitor and if I am using 'alsa_output
.pci-0000_02_00.1.hdmi-stereo-extra1' as my default sink, audio plays
correctly.
I have set up a .desktop file to launch a game in a new xsession using the
following:
/usr/bin/xinit /usr/bin/wine /mnt/1tb/WoW/WoW.exe -- :3 vt8
If I run this script, pulseaudio changes the sink to 'alsa_output.pci-
0000_00_1b.0.iec958-stereo' automatically, so I get no audio from my
application via my monitor. If I hook a device to the s/pdif port I do
get the audio. I am a member of the 'audio' group and this worked
properly in 17.04 but has broken after a clean install of 17.10.
$ pacmd list-sinks | grep name:
name: <alsa_output.pci-0000_02_00.1.hdmi-stereo-extra1> <-----what I
want to stay as default
name: <alsa_output.pci-0000_00_1b.0.iec958-stereo> <-----what the sink
switches to when starting a second X session.
