There's no audio

Video works, sound does not.

The fastest diagnosis is the speaker button in the live view's top bar. Its state tells you which of the three causes you have before you touch anything on the computer.

1. Tick Audio Stream in Premiere Pro

The orange state means exactly one thing: the plugin played for 1.5 seconds and Premiere Pro sent it no audio, so it told the phone that audio is off at the host.

Orange icon, orange ring and a white-on-orange exclamation badge. This is a distinct state from a plain mute — it means do something in Premiere Pro.

Tap the orange button and the app opens a Turn on audio walkthrough. The fix it describes:

Audio Stream is a column in the device table, next to Video Stream — one checkbox per column on the PreviewMonitor row. There is no separate "Audio Device" section or checkbox anywhere in Premiere Pro's preferences; if you are hunting for one, that is why you cannot find it.

This step is Premiere Pro only. After Effects has no audio path at all — see After Effects has no audio at all below. There is nothing to tick in Preferences → Video Preview.

2. The free tier gives ten-second samples

On the free tier, audio is not continuous. The speaker button carries a small lock badge and the stream is silent until you ask for a sample.

The lock badge appears only when the host has audio switched on and you are on the free tier — a locked feature, not a broken one.

Tap the button and you get 10 seconds of audio. Two details are worth knowing:

• The countdown starts on the first audible frame, not on the tap. If the timeline is paused or sitting in a silent stretch, the badge shows … and no time is burned. Once real audio arrives the badge switches to a countdown — 7s, 6s and so on.
• If nothing audible arrives within a minute, the sample is abandoned quietly. No upsell, no time lost, tap again whenever you like. There is no limit on how many samples you can take.

When the ten seconds run out the audio fades over 0.3 seconds, the stream returns to silence and the upgrade options appear.

3. The stream is muted on the phone

On Pro with host audio on, the speaker button is a plain mute toggle. A crossed-out speaker with no badge and no orange means you are simply muted — tap it.

Two things are easy to get wrong here:

• There is no separate mute control. The same button does the work, and it only behaves as a mute when you are on Pro and the host has audio enabled. Outside those conditions the tap does something else — opens the setup sheet, or starts a sample.
• The Audio card in the settings panel is not a mute. Open the gear and the Audio card holds a single Sync picker with Low Latency and Lip Sync. That changes how much the phone buffers before playing, nothing else.

Mute is not persisted, so a Pro session always starts audible and a forgotten mute cannot silently kill your audio tomorrow.

Also check the obvious: the iPhone's own volume, and its physical Ring/Silent switch.

4. The sequence itself is silent

Worth eliminating before going further:

• The sequence has no audio track, or the track is muted or soloed away in Premiere Pro.
• Premiere Pro's own master output is muted.
• The clip is a still or a graphic.

If Premiere Pro's own speakers are silent, the phone will be too.

5. Route and interruption behavior

The app plays through the standard iOS playback session with Bluetooth A2DP and AirPlay allowed, so:

• Bluetooth headphones and AirPlay work. Connecting or disconnecting a device is handled — the engine restarts on the new route.
• Phone calls, Siri and alarms pause the audio and it resumes when the interruption ends.
• Wired headphones being unplugged stops playback the way iOS normally does, then recovers.

6. After Effects has no audio at all

This is worse than it looks, because the phone cannot tell. The plugin only reports "host audio is off" from the Premiere Pro path, so with After Effects the speaker button never turns orange — it behaves like a normal mute toggle, or shows the free-tier lock, and then produces silence forever. Some in-app help text also directs After Effects users to Preferences → Video Preview to enable audio; there is nothing there to enable.

If you need to hear an After Effects comp, monitor it locally.

7. Confirm from the log

On Windows, the plugin's verdict is one line in %LOCALAPPDATA%\PremiereLive\plugin.log:

findstr /C:"SetAudioOutputEnabled" "%LOCALAPPDATA%\PremiereLive\plugin.log"

SetAudioOutputEnabled: 1 means audio is flowing out of Premiere Pro. SetAudioOutputEnabled: 0 means 1.5 seconds of playback elapsed with no audio delivered — the Audio Stream checkbox is the first thing to check.

Two more useful lines:

• QueryAudioMode: idx=0 rate=48000 ch=2 — Premiere Pro asked for the audio format, so the audio path is at least being negotiated.
• StartListening control=:47100 video=:47101 audio=:47102 — the audio socket is up. Audio rides UDP 47102.

On macOS there is no log file; read it with Console.app or

/usr/bin/log show --predicate 'subsystem == "com.premierelive.plugin"' --last 10m --info
