Chrome/chromium browser doesn’t detect microphone source from pulseaudio

[mkrisk]

Hi,

I am trying to make the microphone forwarding of NoMachine to work in the Chrome/Chromium browser. My setup:

• Server side: Debian 9.1.0 (64-bit), Xfce desktop, nomachine-workstation: 5.3.10-7, chromium 60.0.3112.78-1~deb9u1, firefox 52.3.0esr, default NoMachine configuration
• Client side: Windows 10, NoMachine Enterprise Client 5.3.10

I start a new NoMachine “virtual desktop” session (UDP disabled) and then enable microphone in the NoMachine settings.

When I test the microphone input in an xterm with “arecord -vv /dev/null” – the microphone works fine. However, in both Firefox (with default settings) and Chrome (with default settings) the microphone is not available. Tested on

For Firefox the problem gets solved if I set “media.navigator.audio.full_duplex” to false in the firefox settings. The Firefox then detects “nx_voice_out.monitor” as microphone and works fine.

With Chromium (and also Chrome) it doesn’t work and I didn’t find any setting or configuration option that would make it work. Is there something I can do to make the microphone source provided by the NoMachine pulse-audio server work with the Chromium/Chrome browser?

Unfortunately, this key is not available in Chrome (Chrome developers would need to answer why that is). We’ll look into this further, and thanks very much for pointing it out.
