There is no sound during playback (preview) in Adobe Premiere Pro CS3, CS4, CS5, CS5.5, or CS6 on Windows or Mac OS.
This document has two troubleshooting sections. Which section you use depends on whether sound is missing from all clips or only from some clips. If sound is missing from all clips in all projects, then go to Sound Is Missing From All Clips. If sound is missing only from certain clips, or only from clips in a certain project, then go to Sound Is Missing From Some Clips.
Note: If you don't know whether sound is missing from all clips, then you can perform a test by creating color bars with a 1-kHz tone:
Sound is missing from all clips
Your computer could have more than one device can play back audio; for example, an internal speaker, external speakers, or headphones. Set your preferred device as the system default sound playback device, and then verify that its volume is not muted or set low.
- Look at the options in the Default Device pop-up menu. These options are the audio drivers that Adobe Premiere Pro can use to output sound, and there are two basic kinds:
- Look at the list of devices in the Output tab of the Audio Hardware Settings window. (See this page .)
To enable or disable an output device, click the box to the left of the device. A check mark in the box indicates that the device is enabled.
Enable the device that you prefer, and then disable any other devices in the list. (For best results, enable the device that you chose as the system default playback device in Task 1.)
If you don't hear sound after completing the tasks above, then the driver for your computer's sound card could be out-of-date. Many sound card manufacturers frequently update their software drivers. Contact the manufacturer of your sound card or the manufacturer of your computer for an updated driver, or download one from the manufacturer's website. When you have updated the driver, repeat solutions one through three above.
If no ASIO driver is installed and one is available for your sound card, then download and install the ASIO driver.
Sound is missing from some clips
If sound is missing only from certain clips or only from clips in a certain project, then do the following tasks in order:
In the Timeline panel, look at the box at the far left or far upper left of each audio track's header. If no speaker icon appears in this box, then the track is disabled. To enable a disabled audio track, click in the box. A speaker icon appears.
In the illustrated example below, the speaker icon (circled) indicates that the Audio 1 track is enabled. On the right side, the empty box indicates that the Audio 1 track is disabled:
Use the Audio Mixer to determine if an audio track is muted or has low volume, and to increase the volume if necessary.
To open the Audio Mixer, choose Window > Audio Mixer > [Sequence Name].
Verify that individual clips' volume is not muted or low. For instructions, see Adjust Track Volume With Keyframes in Adobe Premiere Pro CS4 Help, or Adjust track volume with keyframes in Adobe Premiere Pro CS5 & CS5.5 Help.
(Mac OS) 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. Some codec publishers are listed on the Apple QuickTime Components page at www.apple.com/quicktime/resources/components.html. 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. (Software you can use to transcode the clips include MPEG Streamclip or QuickTime Player with the QuickTime Pro upgrade.) Then, import the transcoded files into Adobe Premiere Pro.
If you still don't hear audio from one or more clips, the problematic clips could've been encoded with an incompatible codec. See Troubleshoot problems with AVI, MOV, MPEG, or other kinds of video files (Premiere Pro CS4, CS5, and CS5.5 on Windows) for instructions on troubleshooting codecs.
