Part 1. Audio Not Playing for All Clips

If the sound is missing from all clips after importing to Adobe Premiere Pro, then try the following methods.

---1. Check the Default Audio Device

If your computer has more than one device that can playback audio, the Premiere Pro audio not playing may be caused by the wrong audio devices. It often happens when someone switches frequently between headphones and internal speakers. So you need to change the device and then test one by one for more than one device connected.

Just open the “Preferences” tab in Premiere Pro and go to the “Audio Hardware” section.
Find “Default Input” and change the selected device. Click “Yesin the pop-up window. If it is not working, try to choose another device.

Check Default Audio Device

---2. Disable the NewTek NDI Output

If you installed NDI tools on your computer to let you export NDI IP-video straight from Adobe Premiere Pro, you may encounter issues like no audio in Premiere Pro. If the NDI drive is selected as the default and the audio is routed to it, the audio is lost since there is no endpoint. As a result, Premiere Pro no sound issue occurs. To solve it, you need to set the playback settings back to Premiere.

Just open the “Preferences” tab in Premiere Pro and go to the “Playback” section.
Find the “Audio Device” and switch it to “Adobe Desktop Audio” or “Adobe DV” from the drop-down list.

---3. Clear the Media Cache Files

When you import and deal with media files, Premiere Pro builds cache files to improve performance. These cache files use CFA and PEK extensions and links will be made to these cache files in the Media Cache Database. The longer the duration, the larger the database and the cache files. Delete these cache files and database, then re-import and re-link the clips may solve the Premiere sound not playing issue.

Here are two ways for you to clear the media cache.
1. Open the “Preferences” tab in Premiere Pro and go to the “Media Cache” section, click the “Delete” button to directly remove all media cache files.
2. You can also manually delete the media cache files by going to the folder: "C:\Users\[XXX]\AppData\Roaming\Adobe\Common" on Windows or “/Users//Library/Application Support/Adobe/Common” on Mac. Then delete the folders to clear the Media Cache Files and Database.

Re-launch Adobe Premiere and open your project to check the audio is OK now.

Clear the Media Cache Files

* If Premiere Pro still has no audio, you can reset the preferences and the plug-in cache at the same time:
Step 1. Hold on the "Shift + Alt" keys (Windows) or "Shift + Option" keys (Mac OS) while starting the application.
Step 2. Release the "Shift + Alt" keys or "Shift + Option" keys when the splash screen appears.
Step 3. Then a box will pop up and ask if you want to reset. Click “OK”.

---1. Enable the Audio Channel

If the Premiere audio not playing in timeline, that may be because of the muted audio channel. On the left side of the timeline, there are some factors, and the “V1” and” A1” will determine what you can import into the timeline. If only the “V1” toggle is selected, then you can only import the video to the timeline. This will lead you to the Premiere Pro audio not playing in timeline issue.

Enable the Audio Chanel

---2. Unmute the Track

The Mute and Solo button can temporarily silence all other tracks which lead to the Premiere Pro no sound issue. So when the audio not playing in Premiere Pro, remember to make sure to solo or unsolo (mute or unmute) each audio track to check if you selected it accidentally. Also, don’t forget to check the master volume panel and check if you’ve clicked the yellow “S” button by chance. If yes, toggle it off.

Unmute the Track

---3. Convert the Incompatible Formats or Codecs

There is another possible cause of the Premiere Pro not playing audio issue. If your videos in MP4, MOV, AVI, etc. have no audio after being imported to Premiere Pro, the imported clips may contain any codec that is unsupported by Adobe Premiere. So another fix to the no audio in Premiere Pro issue is to check and transcode the video to one of the Premiere Pro supported formats and codecs with a handy video transcoder.
