[SOLVED] Help setting up advanced audio routing (Realtek ALC892)

Hi,

This is a new space for me and I'm having trouble getting started.

I would like to be able to route application audio via a "virtual cable"

I'm not sure how to get alsa/pulseaudio/jack to play together nicely or even correctly set up

What I have is as follows

>> cat /proc/asound/cards
 0 [SB             ]: HDA-Intel - HDA ATI SB
                      HDA ATI SB at 0xfe400000 irq 16
 1 [NVidia         ]: HDA-Intel - HDA NVidia
                      HDA NVidia at 0xfe080000 irq 34
 2 [Device         ]: USB-Audio - USB PnP Audio Device
                      USB PnP Audio Device at usb-0000:00:13.0-3, full speed

I would like to use the USB-Audio as plug and play input if possible and the HDA ATI SB as output

I believe I need to update /etc/asound.conf and have attempted to follow information provided here
https://wiki.archlinux.org/index.php/Ad … chitecture
and
https://wiki.archlinux.org/index.php/JA … ection_Kit

But I haven't been able to get a working configuration

Card codec information might be useful if someone has worked with this chipset before so pasted below.

Please let me know if any information would be helpful.  I really appreciate help on this.

Re: [SOLVED] Help setting up advanced audio routing (Realtek ALC892)

Seeing I have no reply makes  me nervous so here's some additional info.
I am aware this is a mess, but I did state I had no idea what I was doing...
I have a working pulseaudio configuration with the following setup

/etc/asound.conf

pcm.pulse {
  type pulse 
}
ctl.pulse {
  type pulse 
}

pcm.!default {
  type pulse 
}

ctl.!default {
  type pulse
}

~/.asoundrc

pcm.!default {
    type plug
    slave { pcm "pulse" }
}

Re: [SOLVED] Help setting up advanced audio routing (Realtek ALC892)

Your .asoundrc is superfluous in light of the asound.conf you can remove it.

I'm unsure to as to what you are asking/trying to achieve. Routing output over the internal card and recording/input via USB is quite trivial so I'm unsure as to where you are stuck. You might be interested in installing pavucontrol and looking through it's possibilities. If what I assumed you want to do is true, that should make it quite clear as to what you can and should do.

If that isn't all you are trying to achieve try to explain what your end goal is, without worrying about the details of how to achieve that, we can work that out, but we need a general overview, FWIW you might also want to post 

pacmd list-cards
pacmd list-sinks
pacmd list-sources
#During playback/recording
pacmd list-sink-inputs
pacmd list-source-outputs

Re: [SOLVED] Help setting up advanced audio routing (Realtek ALC892)

First of all, thank you so so much for replying V1del! (And I love the DBZ reference)

Really I would probably be fine with just pulseaudio if I could figure out how to route audio properly but I had searched online and results were turning up to use jack.

I would like to route application audio from lets say VLC into OBS as a VLC channel so if I were to have a web browser open then OBS would only record audio from the VLC audio
At the same time I would still like to be able to hear/monitor the VLC audio & web browser audio from my speakers.  It should be simple enough, just not for me haha.

I've installed pavucontrol and I really do like it, but I don't see the option to add/configure a sink.

As requested here's my output:

Also thank you for pointing the .asoundrc
I currently have this in my asound.conf, and removed the .asoundrc file, still don't know if it makes sense to be honest.

pcm.usbmic {
  type hw
  card Device
}
pcm.sbaudio {
  type hw
  card SB
}
pcm.jack_out {
  type plug
  format S32_LE
  channels 2
  rate 48000
  slave pcm.sbaudio
}
pcm.jack_in {
  type plug
  format S32_LE
  channels 1
  rate 48000
  slave pcm.sbaudio
}
pcm.jack_mic_in {
  type plug
  format S32_LE
  channels 1
  rate 48000
  slave pcm.usbmic
}

pcm.jack {
    type jack
    playback_ports {
        0 system:playback_1
        1 system:playback_2
    }
    capture_ports {

Re: [SOLVED] Help setting up advanced audio routing (Realtek ALC892)

Ah well yes that's trivial (though there doesn't exist a simple GUI for it indeed) (FWIW you might want to revert the asound.conf to what you had originally if we want to stay in pulse-land) : 

pactl load-module module-virtual-sink sink_name='"My virtual sink"' master=alsa_output.pci-0000_00_14.2.analog-stereo

, and select the new sink/monitor in OBS if that works and you want to make that persistent, add that line (maybe remove the ' , but the " should stay if you intend to have spaces in the sink name) to the end of your /etc/pulse/default.pa

To be frank I wasn't immediately aware of this level of simple at first and it seems to be generally quite burried documentation wise, I was originally thinking a null/combine sink combination but when randomly tab-completing through the module list this turned up and seems to do exactly what you want.
