Summary
Classroom computer does not play audio through the installed speakers. When waking from sleep, Windows will sometimes switch to the first audio output device it sees, rather than the previously-selected output. This will cause audio to be played from the computer itself, a monitor, or to not be audible at all.
Body
If the volume level on the computer and the A/V control system is turned up, but the computer audio does not play through the system speakers, the default audio device may need to be changed in Windows:
- Click Start.
- Type in mmsys.cpl
- Press Enter.
- Click the Playback tab.
- Right-click in the box and check Show Disabled Devices.
- Right-click on each listed device and select Test to play a test sound through that device (if the device is disabled, select Enable, then Test).
- If the test sound played through the system speakers when testing one device, right-click on that device and select Set as Default Device.
- If none of the listed audio devices played the test sound through the system speakers, restart the computer and check if any new audio devices have been added to the list​.
