Follow the instructions in this document if you don't hear sound from speakers connected to your computer when you play clips in Adobe Premiere Elements 7.
This document has two troubleshooting sections. Which section you use depends on whether sound is missing from all clips or only from some clips.
Note: If you don't know whether sound is missing from all clips or only some clips, then you can perform a test by creating color bars with a 1-kHz tone:
If sound is missing from all clips in all projects, then do the following tasks in order:

2. Adjust the audio hardware driver settings in Adobe Premiere Elements.
3. Update the driver for your sound card, or install an ASIO driver.
If you have completed all the tasks above and you still do not hear sound, then the driver for your computer's sound card could be outdated. 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 the steps in this section.
If no ASIO driver is installed and one is available for your sound card, then download and install the ASIO driver.
If sound is missing only from certain clips or only from clips in a certain project, then do the following tasks in order:
1. Check for muted or low track volume.
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.
2. Check for muted, low-volume, or disabled clips.
Verify that individual clips' volume is not muted or very low. For instructions, see Adjust volume in the Timeline in the Adobe Premiere Elements 7 Help.
Also verify that individual clips are not disabled. For instructions, see "Enable and disable clips in the Adobe Premiere Elements 7 Help.
3. Check for clips with incompatible codecs.
If you completed all of the steps above and you still don't hear sound, then the problematic clips could've been encoded with an incompatible codec.
See Troubleshoot problems with AVI, MOV, MPEG, VOB, and other kinds of video files (Adobe Premiere Elements 7) (kb407935) for instructions on troubleshooting codecs.
