( continuation of a thread about my 'dual screen' setup: 'Automatic
selection of an audio sink depending on value of ENV variable ' )
I've got 1 X server running and 2 screens: 0.0 and 0.1; 2 soundcards:
leszek at leszek-desktop:~$ pacmd list-sinks | grep name | grep output
name: <alsa_output.pci-0000_00_07.0.analog-stereo>
name: <alsa_output.pci-0000_01_06.0.analog-stereo>
I would like to set up Pulse so that whenever I'm in 0.0, sound gets
routed to alsa_output.pci-0000_01_06.0.analog-stereo, and whenever I
work in 0.1 - to alsa_output.pci-0000_00_07.0.analog-stereo.
I've been advised that Pulse is able to get its default sink from X
properties of the root window. Let's try then:

PULSE_SINK(STRING) = "alsa_output.pci-0000_00_07.0.analog-stereo"
PULSE_SERVER(STRING) = "leszek-desktop"
PULSE_SESSION_ID(STRING) =

leszek# xprop -root | grep PULSE ## on TV "0.1"
(nothing)
And sound always goes to alsa_output.pci-0000_00_07.0.analog-stereo. pax11publish ignores screen numbers.

But maybe I can set the properties manually? Let's try then:
## on 0.0
leszek# xprop -root -f PULSE_SINK 8s -set PULSE_SINK alsa_output.pci-0000_01_06.0.analog-stereo
leszek# xprop -root | grep PULSE

PULSE_SERVER(STRING) = "{571eae318b6377f95367e6524abdec09}unix:/home/leszek/.pulse/571eae318b6377f95367e6524abdec09-runtime/native"
PULSE_SESSION_ID(STRING) = "571eae318b6377f95367e6524abdec09-1256446499.571891-1748126058"

## on 0.1
leszek# xprop -root -f PULSE_SINK 8s -set PULSE_SINK alsa_output.pci-0000_00_07.0.analog-stereo
leszek# xprop -root | grep PULSE
PULSE_SINK(STRING) = "alsa_output.pci-0000_00_07.0.analog-stereo"
So far so good, but when in screen 0.1 I try launching, say, Audacious - its sound still gets sent to alsa_output.pci-0000_01_06.0.analog-stereo.
