Hi Sandra English,
Thanks for reaching out to Microsoft Q&A Forum. I understand your Bose speakers are not showing as connected on your Windows 11 PC and there is no sound.
Please make sure you already tried the steps suggested by the Q&A Assist message above. In addition, please try to follow these steps:
1, Go to Settings > System > Sound > Output and manually select your Bose speakers as the default output device.
2, Go to Settings > Bluetooth & devices > Devices, remove the Bose speakers if they are listed, then restart the PC.
3, After restarting, turn on the Bose speakers, put them into pairing mode, then go to Settings > Bluetooth & devices > Add device and reconnect the speakers.
4, Press Windows + X > Device Manager > Sound, video and game controllers, right-click each audio device, then select Uninstall device and restart the PC to allow Windows to reinstall audio drivers automatically.
5, Go to Settings > System > Sound > Volume mixer and confirm that the system volume and app volume are not muted or set to very low output.
6, Go to Settings > Windows Update > Check for updates and install any available driver or optional updates related to audio or Bluetooth.
