I (have to) use your WebClient on Debian 9.5 and experience issues since the last google-chrome update. The message from your web client is "Could not start audio source". However, it worked before. After downgrading chrome it did not start working again.

My setup:
  • OS: Debian 9.5
  • Browser: google-chrome (ATM downgraded to 69.0.3497.100), 64bit.
  • Jabra Engage 65 headset

The browser console also only states: DOMException: Could not start audio source.

Playing audio in general works, also from chrome. Recording also works, if it works from chrome I cannot tell, its the only service I use which uses audio. I also tried in FireFox. There it works, but I have to switch the audio sink / source after each start (Internal audio to Headset), which is PITA.

By the way: While I was writing this ticket, the headset started ringing for an incoming call, so audio seems to work. But when I click the accept call button, the error message pops up, but it keeps ringing.

I need help identifying the issue, as the error message gives no clue.
 
Hi Michael,

If you upgrade to V16 Update 4, and use the latest version of Chrome, can you confirm if this still happens?
 
Also happens with Chrome Version 79.0.3945.79 (Offizieller Build) (64-Bit) and 3CX 16.0.4.493

And update to Chrome Version 79.0.3945.88 (Offizieller Build) (64-Bit) also didn't work
 
@Michael-K and @iconline

Please provide more info:

  • What version of 3CX are you currently running?
  • What desktop OS are you using to access the webclient?
 
3CX 16.0.4.493 on Windows Server 2012 R2
Windows 10 V1903 18362.535
 
Hi @iconline

Can you please first check that the browser can have access to audio devices?

You can google for "check my mic online" and try a website that tests your microphone and plays back what you say?
 
Although the soundcard functioned, I switched to another one, now it works.
