We are experiencing a long delay when trying to switch between external and internal microphones as audio input in Google Meet. Steps to reproduce: Join the same meeting from Chrome and Safari on the same computer. Turn on the speaker in the meeting in Chrome. Turn off the microphone in Chrome. Turn off the speaker in Safari. Turn on the microphone in Safari. Speak while switching between two different microphone sources. Check how long it takes until you hear your echo from Chrome. Now, do the same but reversed: Turn on the speaker in the meeting in Safari. Turn off the microphone in Safari. Turn off the speaker in Chrome. Turn on the microphone in Chrome. Speak while switching between two different microphone sources. Check how long it takes until you hear your echo from Chrome. I tried using an Airpod and using a wired Sony headphone as the external source. I also tried in Firefox and Chrome. The delay of switching audio input in Safari is significantly longer than the delay in other browsers. Here are some of my experimentation results: With Airpods using bluetooth: In Chrome Airpod to internal microphone: 1-2s Internal microphone to Airpod: 4s In Safari Airpod to internal microphone: 4s Internal microphone to airpod: 6-7s In Firefox Airpod to internal microphone: 1s Internal microphone to airpod: 2s With Wired Sony headphone In Chrome Airpod to internal microphone: Almost instantly Internal microphone to headphone: Almost instantly In Safari Airpod to internal microphone: 2s Internal microphone to headphone: 3-4s In Firefox Airpod to internal microphone: Almost instantly Internal microphone to headphone: Almost instantly
