<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"> <html><body style='font-size: 10pt; font-family: Verdana,Geneva,sans-serif'> 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? <div> <a href="mailto:jenni@surefoot.com">Jenni Knoell</a> Network Administrator <img src="cid:43c7d35f617590234dfc639314d6e292@surefoot.com" alt="" width="0" height="5" /> Surefoot Main Office <a href="http://maps.google.com/?q=1500%20Kearns%20Blvd,%20Park%20City,%20UT%2084060"><img title="Google Maps" src="cid:08d7d3d70995344fbbdc298c696ed037@surefoot.com" alt="Google Maps" border="0" /></a> 1500 Kearns Blvd., Suite A-50 Park City, UT 84060 P: (435) 655 8110 x109 F: (435) 649 0663 <img src="cid:f0b02f56d9129ff7314851d004f9e272@surefoot.com" alt="" width="90%" height="1" /> <img src="cid:43c7d35f617590234dfc639314d6e292@surefoot.com" alt="" width="0" height="2" /> Visit us: <a href="http://www.surefoot.com"><img title="Surefoot Homepage" src="cid:2931dc22236cb8bed4ab4c33b0637286@surefoot.com" alt="Surefoot Homepage" border="0" /></a> <a href="http://www.skiboots.com"><img title="Online Shop" src="cid:ce78add2dc9951b815984ef396f08c08@surefoot.com" alt="Online Shop" border="0" /></a> <a href="https://www.facebook.com/customskiboots"><img title="Like us on Facebook" src="cid:fdcf20ab57008bf1ef84d0a508cfc73a@surefoot.com" alt="Like us on Facebook" border="0" /></a> <a href="https://twitter.com/#!/surefootskiing"><img title="Follow us on Twitter" src="cid:c0902cc1c55863794b166f0b686166fc@surefoot.com" alt="Follow us on Twitter" border="0" /></a> <a href="http://www.linkedin.com/company/626481?trk=tyah"><img title="LinkedIn" src="cid:02975b0b40586f870aca9dd74e53f182@surefoot.com" alt="LinkedIn" border="0" /></a> <a href="https://plus.google.com/109265101162931134389/posts"><img title="Follow us on Google+" src="cid:8d703deab5cedcf7f9915e756263cc14@surefoot.com" alt="Follow us on Google+" border="0" /></a> <a href="http://www.youtube.com/surefootskiing"><img title="Surefoot Youtube Channel" src="cid:3b22e35c5157489454cae1be979ab2ce@surefoot.com" alt="Surefoot Youtube Channel" border="0" /></a> </div> </body></html>
