Unable to get Audio input work in Ubuntu

[DineshkumarS]

I'm unable to get Audio in device work in HOrizon ubuntu 16.04 desktop.

But AUdio output is working as expected.

I have enabled RTAV in view agent configuration.

HOw can i make it work? SHOuld i use RTAV or USB audio redirection.

Please suggest

Audio input is not based on the USB redirection function. If you want this feature enabled, you must select it during installation, " -a yes", while it should be enabled by default. You must select the system default audio in device "PulseAudio server (local)" in your application for the audio input.

If it still doesn't work could you provide more information and logs?

I've followed the same procedure during installation by passing "-a yes" during linux agent installation. But while selecting the audio input it is showing blank and its blank for audio output too.

Linux version: 18.04
HOrizon version: 7.6

Let me know what logs I should provide for troubleshooting this.

I have a similar problem. Client on Windows (5.4.2 build-15936851) - > Ubuntu 18.04 (agent version 7.12.0-15765535).

What do I need to do to make the microphone appear in available devices?

The problem was resolved. :

./install_viewagent.sh --help

-a        yes|no <Install|Bypass audioin support>. Default is no.

./install_viewagent.sh -a yes

I didn't find anything about it in the documentation Configuring Real-Time Audio-Video
