Audio output problems are often routing problems. The sound may be playing, but it is going to a monitor, Bluetooth headset, docking station, or muted device instead of the speakers you expected.
An online speaker test can help confirm whether the current output setup is producing sound. Play a test tone and listen for the expected left and right channels. If you hear nothing, the issue may be output selection, volume, mute state, or device connection.
This is useful before presentations, online classes, interviews, and recordings. It is also helpful after switching between headphones and speakers, joining a new conference room, or reconnecting Bluetooth devices.
If the speaker test works but a specific app stays silent, check that app audio settings. If the speaker test does not work, check the operating system output device and hardware connection first.
The test does not need to be complicated. For most people, the practical question is simple: can I hear sound from the device I plan to use? Answering that before a call starts can prevent an awkward first minute.
