Video conference platforms audio/video bandwidth
If you are using a videoconferencing platform in browser and there is no audio but the video is working perfectly and high quality, could it be down to internet connection issues? I think that video is many many times more demanding on the connection than audio, so if there were connection problems you'd sacrifice video before audio, or have i misunderstood?

That's certainly been my experience. Video wil get blocky and slow to update long before audio suffers. A modern audio codec can get very good audio quality into 16kbit/s or less, and adequate audio into half that, it's unlikely that your internet connection is that bad.

The audio on my end was perfectly fine, but my client couldn't hear me. Thanks for your response. |

What system is it? In a former life I worked for one of the big telepresence firms on some of this stuff.
The problem is that "real" video conferencing systems rely on a mechanism called "quality of service" to try to keep things on track. You'd ensure that audio / video is prioritised well above all other types of traffic, like web browsing or email. That's only possible when you control things from end to end, e.g. you're sitting at your desk at the office and so are the other people. There's no such mechanism to prioritise it when you're connected via the internet. If there is no audio at all, not even clicks or pops, then I'd say something else is wrong. |
