Chris, If your Altec speakers are working on another computer but not on your desktop, there could be several reasons why this is happening. Here are some steps you can take to troubleshoot and potentially fix the issue: 1. Check Speaker Connections: - Ensure that the speakers are plugged into the correct audio jack on your desktop. Try plugging them into different audio ports to see if that makes a difference. 2. Check Volume Settings: - Make sure that the volume is not muted both on the speakers themselves (if they have volume controls) and on your desktop. Check the volume settings in the system tray and the sound settings in the Control Panel. 3. Update Audio Drivers: - Outdated or corrupt audio drivers can cause sound issues. Try updating the audio drivers on your desktop. You can do this through Device Manager or by visiting the manufacturer's website for the latest drivers. 4. Run the Sound Troubleshooter: - Windows has a built-in sound troubleshooter that can help identify and fix common sound issues. - Go to Settings > Update & Security > Troubleshoot > Playing Audio, and run the troubleshooter. 5. Check Default Playback Device: - Make sure that the Altec speakers are set as the default playback device. - Right-click on the speaker icon in the system tray, select "Open Sound settings," and choose your speakers as the default playback device. 6. Check for Windows Updates: - Ensure that your Windows system is up to date with the latest updates. Sometimes, updates can resolve compatibility issues impacting sound. 7. Test with Different Software: - Try playing audio from different sources (e.g., YouTube, music player) to see if the issue is specific to certain applications. 8. Hardware Check: - If possible, try using different speakers or headphones on your desktop to determine if the issue is with the speakers or the computer's audio output. By following these steps, you should be able to diagnose and hopefully resolve the issue with your Altec speakers on your desktop.
