When there's no sound from a projector, but the video display is working, it indicates that the issue may be related to the audio connection or configuration. Checking whether the audio cable is connected properly is a logical next step because loose or weak connections can result in audio loss. If the connection was previously working and has suddenly failed, it's less likely that the projector's audio hardware has failed. Therefore, checking physical connections is preferable over more complex solutions like driver reinstallation or system configuration changes.
