Hi,
I have another sound card for my external monitor and I'd like to change my default output sink when switching from one monitor to the other:
echo set-default-sink 0 | pacmd (laptop) echo set-default-sink 3 | pacmd (ext. monitor)
What I need is a hook where I can issue these commands when I change to a workspace which is on the other monitor. Is this possible (4.5.1)?
Best regards
New answer: Yes this is possible, but you'll have to cross the line between configuration and writing code. You could subscribe to the workspace event with some IPC-library. Feel free to post your solution :)
Old answer:
AFAIK, this is not possible. But there is also a more correct level to address this wish: udev. Then you can have your machine react to the hardware event 'new sound card', instead of some unrelated but correlated change in a user application.
Someone with a very similar wish has written about it: http://stavrakisblog.blogspot.de/2012...
The sink should change depending on which screen my app (mplayer) is. If the window is on my laptop I'd like to hear the sound from it. If I move the window to the ext. monitor the sound should "follow". The necessary commands are in my above comment of the original question.
A toggle command has to know the pulse audio index of the program in question. I also need another running server process for the IPC callback, right? What I really miss is a possibility to issue shell commands on callback in the i3 config file, or an integrated extension language to do such things.
If you are talking about getting the sound output to change dynamically, you might get answers on different forums. For i3, considering you know which one to trigger this change, you can make the keybind do something else:
bindsym Mod4+1 exec ~/.i3/workspace 1
And for the workspace script:
#!/bin/bash
#
# do whatever you want
#
i3-msg "workspace $1"
I can start mplayer and redirect sound directly with the -ao option:
mplayer -ao pulse::$([ "$output" == "VGA1" ] && echo 3 || echo 1) myvideo.mp4
But how can I find out on which output the window will open? I'm still looking for a simple way to switch sound depending on the monitor where mplayer is started.

Actually my commands are wrong but the should be issued on **output** change. The correct command is 'move-sink-input index sink-index'. Sink 0 is my laptop and sink 3 is my monitor.
