Hi, MrNate Burney Jr
A connected device can still be silent if the speaker or app is muted, or audio effects are interfering. Here are some suggestions you can try:
First, turn up the volume using the buttons on your JBL speaker, then check the volume inside the app playing your music or video. These controls can be separate, so check both even if the computer’s volume is already turned up.
Next, try turning off audio enhancements. On Windows 11, open Settings > System > Sound, select your device under Output, and set Audio enhancements to Off, if available. On Windows 10, open Sound Control Panel > Playback, select the device, choose Properties > Enhancements, and check Disable all enhancements. Test the sound again afterward.
If it’s still silent, run the Audio troubleshooter in the Get Help app.
Could you share the adapter’s brand and exact model, and whether it plugs into the computer’s USB port or the speaker’s audio jack? That will help narrow down the next step.
