pulseaudio split front and rear audio

Hello fellow archers!
I'm trying to have to separate sinks so that I am able to route some applications to my speakers, using the audio jacks from the back of my case, while other apps should play in my headphones using the jack from the front panel.
Right now what I hear in the speakers(back) I also hear in my headphones (front)
I have pulse audio installed and I tried this Splitting front/rear from the wiki.
So in my /etc/pulse/default.pa I added:

load-module module-remap-sink sink_name=speakers remix=no master=alsa_output.pci-0000_00_1b.0.analog-stereo channels=2 master_channel_map=front-left,front-right channel_map=front-left,front-right
load-module module-remap-sink sink_name=headphones remix=no master=alsa_output.pci-0000_00_1b.0.analog-stereo channels=2 master_channel_map=rear-left,rear-right   channel_map=front-left,front-right

Running pacmd list-sinks lists this:

Now when I route vlc to play on the remapped sink, speakers, it's the same as before: I hear the same thing in my speakers and my headphones.
When I route vlc to play on the second remapped sink, headphones, I hear nothing at all, neither in my speakers or my headphones.

other info:

What am I doing wrong ?

Re: pulseaudio split front and rear audio

Can't get it to work either, but it is not too important for me.

Re: pulseaudio split front and rear audio

Just to confirm, you are sure the front and rear jacks are capable of working simultaneously, right? Because not all audio controllers allow this.

Re: pulseaudio split front and rear audio

I wasn't able to find a solution for this under Arch.
It's working under Win 7 though ... but i'm 95% of the time under arch...

I am having the exact same issue with my speaker/headset configuration.
Either sound on both devices (headset and speakers),
or no sound (even though pavucontrol shows some activity).

Anyone found any solution yet?

Re: pulseaudio split front and rear audio

I'm really wondering why nobody has found a solution to this. I'm hanging on the same thing and it is annoying.

It should just be some port splitting into two sinks, but I just can't find any solution. Maybe there is missing support for this from pulseaudio?

Just to be clear:
One sink in pulseaudio, stereo configuration, 2 ports listed (with list-sinks): analog-output-lineout and analog-output-headphones

With alsamixer, I can change the volume of lineout and headphones separately, so there must be some way to split it in pulseaudio, too.
