[pulseaudio-discuss] Problem with remapping sinks to separate outputs

[Jenni Knoell]

Hi everyone 

I've been stumped on that for a few months now and can't figure it out
anymore. 

What I am trying to do is separate front left/right, center left/right
and back left/right into separate stereo channels. Oddly, this used to
work until I reinstalled Kubuntu a few months ago (failed HD). Now it
fails in a strange way. 

I have and use three outputs: 

ALC889 built-in sound chip, using the analog 7.1 outputs 

HDMI via nVidia GPU (HDMI outputs not always connected) 

Bluetooth Headset on-demand (i.e. not always connected) 

I've added these lines to the end of /etc/pulse/default.pa, everything
else is completely default: 

# Split outputs and add echo cancellation service
load-module module-remap-sink sink_name=earphones
sink_properties=device.description="Earphones" remix=no
master=alsa_output.pci-0000_00_14.2.analog-surround-71 channels=2
master_channel_map=side-left,side-right
channel_map=front-left,front-right
load-module module-remap-sink sink_name=headset
sink_properties=device.description="Headset" remix=no
master=alsa_output.pci-0000_00_14.2.analog-surround-71 channels=2
master_channel_map=rear-left,rear-right
channel_map=front-left,front-right
load-module module-remap-sink sink_name=speakers
sink_properties=device.description="Speakers" remix=no
master=alsa_output.pci-0000_00_14.2.analog-surround-71 channels=2
master_channel_map=front-left,front-right
channel_map=front-left,front-right
load-module module-echo-cancel 

And that's where it gets odd. The "earphones" and "speakers" sinks work.
The "headset" sink does not, it's silent even though it does show up as
output in both pacmd list-sinks and in the KDE mixer. 

The weird thing: If i go directly to the soundcard sink, I can play
sounds on all channels - separately or simultaneously. And of course,
this worked before, why doesn't it work now? What am I missing?
