Playback issues due to missing sound from some of the clips

Last updated on Jun 23, 2025

Learn how to troubleshoot if audio is missing from all clips across all projects.

Check for muted or low track volume

Use the Audio Mixer or Timeline panel to determine if an audio track is muted or has low volume, and to increase the volume if necessary.

  1. Open the Audio Mixer, select Window > Audio Clip Mixer > [Sequence Name] or Window > Audio Track Mixer > [Sequence Name], or in the Timeline panel, look at the box at the left.

  2. If the M next to any of the tracks is highlighted, the audio is muted. Select M to turn sound on.

Check for muted, low-volume, or disabled clips

Verify that the individual clip's volume is not muted or low. Learn more about monitoring clip volume and pan using Audio Clip Mixer.

Also, verify that individual clips are not disabled using the following method:

  1. Select one or more clips in the Timeline panel and select Clip > Enable

  2. A check mark next to Enable indicates that the selected clips are enabled.

    Disabled clips appear dimmed in the Timeline panel.

Check for clips with incompatible codecs

If you completed the steps above and you still don't hear sound, the problematic clips could have been encoded with an incompatible codec. Codecs are algorithms for compressing audio and video data. Many different codecs exist. Sometimes, Adobe Premiere Pro can't decode files that were encoded with a poorly designed codec or a codec that is not installed on your computer.

You can download third-party codecs from codec publishers' websites. If the codec used to create the clips isn't available as a QuickTime component, use other software to transcode them with a different audio-encoding format. Then, import the transcoded files into Adobe Premiere Pro.

Missing audio or video in the footage

Sometimes, when you import the footage, the footage may be missing audio or video. Learn more about the no sound during playback issue.
