Guitar sound in zoom.us conference

[hdr]

I want to have the output from guitarix - or any other guitar amp software - to go through a zoom.us conference. Additional to the sound of my USB-webcams mic.
I'm using a Behringer UMC204HD USB interface.

I was not able to manage that. Does anybody have experience with that?
The guitar sound is not transfered to the video conference.

You can probably do this with the jack-pulseaudio bridge ,carla , and a mixer plugin . then set your zoom audio to PulseAudio JACK Source.

I tried this:

my guitar is connected to capture_2.
In Zoom Audio Settings I can choose Jack source (PulseAudio JACK Source) or Webcam C270 Analog Mono for Microphone Select Mic. First option -> guitar sound is available, second option -> my voice is available (through USB webcam mic). How can I get both?

I assume your microphone is 'capture 1'. trying connecting that and routing it to the pulse input

You need to use alsa_in to get your webcam mic to be available in jack, and then you can route it as needed.

No, capture 1 is the first input channel of my interface - which is not connected to anything.
I want to use the microphone from my USB webcam.

How can I get that? Is it a plugin?

alsa_in is command in jack2 package in ubuntu, so most likely also in your distro. Find your webcam interface with

Code: Select all

arecord -l 

and then use it with alsa_in. Run

Code: Select all

alsa_in --help

Find your webcam interface with

Code: Select all

arecord -l 

It's not found:

Code: Select all

$ arecord -l
