    pulseaudio, two output devices...

    I want to put communication applications such as TeamSpeak 3 or skype to my headphones (front panel) and everything else to my speakers (back panel). I was able to do it in windows, however on linux I can't seem to get it to work I managed to get simultaneous output by disabling auto mute mode. I was on the pulse audio IRC and had someone tell me: "you will have to try the multi channel stuff to see if you get different output, the controls are kind of ambiguous" but I don't understand what he was talking about let alone how to do it.
    The output of:

    Re: pulseaudio, two output devices...

    I have it set where I am using "Analog Surround 4.0 Output + Analog Stereo Input" with 2 virtual devices:
    Code:
    pacmd load-module module-remap-sink sink_name=front_stereo master=alsa_output.pci-0000_00_05.0.analog-surround-40 channels=2 master_channel_map=front-left,front-right channel_map=front-left,front-right
    Code:
    pacmd load-module module-remap-sink sink_name=rear_stereo master=alsa_output.pci-0000_00_05.0.analog-surround-40 channels=2 master_channel_map=rear-left,rear-right channel_map=rear-left,rear-right
    But it still plays it on both devices, even if I choose one of the remapped devices. I don't understand.

    Sincerely,
    Patrick Thomas (Timberwolf)

    Just removed the virtual devices the re-added them but with remix set to no. Now the front audio plays on both and the rear does not play on any device.

    Re: pulseaudio, two output devices...

    I think you're getting confused with front/rear thinking that it means front or rear jacks when it really means front speakers and rear speakers in a surround speaker setup (at least, that's what it looks like).

    Are you using USB headphones or do you have regular headphones plugged into the headphone jack?

    Re: pulseaudio, two output devices...

    Both the speakers and the headset are the 3.5mm jacks.

    I put it on Analog Stereo Duplex and used pacmd list-sinks and got the following output:
