When you take a meeting on a remote Mac, sound can reach you by two roads: your remote desktop tool’s audio, and Remote Visio. Most echo and double-audio problems come from both roads being open at once. The fix is almost always the same: turn sound off in the remote desktop tool, and keep the sender page’s speaker on.
Symptom 1: you hear the meeting twice
What it sounds like: every voice arrives twice, a fraction of a second apart.
Why: Remote Visio sends what the meeting plays into Remote Visio Speaker to your device. Your remote desktop tool also forwards the Mac’s sound. They have different delays, so you get two copies.
Fix: turn off sound transmission in your remote desktop tool’s settings. Remote Visio carries the meeting’s sound now, on its own low-latency connection.
Symptom 2: you hear your own voice
What it sounds like: you talk, and a moment later you hear yourself.
Why: the remote tool is still forwarding audio, and some tools even send the Mac’s input back to you.
Fix: the same: turn the remote tool’s audio off.
Symptom 3: the other participants hear an echo of themselves
What it sounds like: people in the meeting complain that they hear their own voice back.
Why: the meeting’s sound comes out of your speakers and goes back into your microphone. Your browser can cancel that, but only when it knows what is playing. On the sender page, echo cancellation is on while the page’s speaker is on. If you turned the page’s speaker off and listen to the meeting through the remote desktop tool instead, the browser has nothing to cancel, and your microphone picks up the meeting.
Fix, one of:
- turn the sender page’s speaker on and the remote tool’s audio off, so the meeting plays through the page and echo cancellation kicks in; or
- wear headphones.
Symptom 4: the meeting hears the room around the Mac
What it sounds like: people hear a TV, an office, typing, in the room where the Mac stands.
Why: the meeting uses one of the Mac’s own microphones, not Remote Visio Microphone.
Fix: in the meeting’s audio settings, choose Remote Visio Microphone. A page that remembered the Mac’s built-in microphone by name keeps it until you change it there. With Use Remote Visio by default on in the extension’s button, a site that asks for any microphone gets Remote Visio’s from the start.
Symptom 5: choppy or robotic audio
Why: packets lost or delayed on the network between your device and the Mac. The Mac’s browser sizes its jitter buffer to the network by itself, so there is nothing to tune on the Mac.
What helps:
- a better network on the sending side: Wi-Fi close to the router, or a cable;
- a direct path between the devices: the sender page’s Debug log says whether the connection is direct, and counts the packets received and lost.
Symptom 6: the first syllable of quiet words disappears
Why: silence suppression (DTX) skips what it takes for silence, and it clips the start of softly spoken words.
Fix: none needed: Remote Visio keeps DTX off and sends your sound continuously. If a meeting service clips the first syllable, it is doing that on its side.
Symptom 7: you hear nothing from the meeting
Check, in order:
- The sender page’s speaker button is not red. Red means off: the meeting is muted on your device only.
- The speaker’s status. Playing the meeting’s sound means it arrives; check your device’s own volume and the speaker’s slider. No meeting uses Remote Visio Speaker yet means the meeting plays somewhere else: choose Remote Visio Speaker in its settings.
- The meeting runs in a Chromium browser on the Mac. The Zoom and Teams apps cannot use Remote Visio Speaker: join from the browser.
A good setup, in short
- Remote desktop tool: screen, keyboard, mouse. Sound off.
- Remote Visio sender page: microphone on, speaker on, Denoise for most rooms.
- Meeting on the Mac: Remote Visio Microphone, Remote Visio Speaker, Remote Visio Camera, from the browser extension.
