Curious question (because we are testing a web site that has two-way voice communication functionality AND video conference/meeting functionality):

Must a video meeting function (assume the video meeting function is inside a web page) need to meet:

1.4.2 Audio Control - If any audio on a Web page plays automatically for more than 3 seconds, either a mechanism is available to pause or stop the audio, or a mechanism is available to control audio volume independently from the overall system volume level.

Is the audio in a web based video or VOIP call considered "automatically playing"? Or, do we need to add a note to clarify that this requirement does not apply to web based VOIP or web based virtual meetings?

(Then I got curious...to see if browsers might give me a way to turn off the incoming audio. I'm working from a Mac...and here is what I experienced:

In one video mtg platform...I just tested to see if there was a way for me to mute the incoming sound.

• In Chrome, I could do it using browser based feature to mute a tab: https://www.wikihow.com/Mute-and-Unmute-Google-Chrome-Tabs
• In Safari, I found a similar feature...but when I tried to mute the tab..it didn't actually work when I was INSIDE the web based video mtg (but my ability to mute audio on a tab in safari DID WORK on a site like YouTube when I had a video playing).
