How to Troubleshoot Sound Speed on a Computer
- 1). Double-check your speaker connections. If one of the audio cables that runs off of your speakers isn't plugged correctly into your computer, this could cause the audio coming from them to speed up or slow down. Make sure all cables are properly connected to their proper inputs and try to play your audio again.
- 2). Update the driver for your computer's sound card. Go to the website of the company that made your sound card and look for your unit's product page. Under the "Support" section, click on the download link for the latest device driver. Once the file is on your computer, double-click on it to install it. Then restart your computer and try to play your audio again.
- 3). Make sure you haven't accidentally sped up or slowed down the media file you are trying to play. Many digital media programs like iTunes or Windows Media Player have features that allow you to play a song or video in slow or fast motion. If this becomes accidentally selected, the audio will also be in slow or fast motion. Click "Stop" to stop your media file from playing and then click "Play" again to allow it to play normally.
- 4). Restart your computer. This will free up system memory when your computer restarts. If your sound was playing too slow or too fast due to an error with not having enough memory to play properly, that error will now be fixed and your sound should return to normal speed.
