• Speaker Error: Moisture, or sometimes when you accidentally drop your iPhone, it loosens the connection of the iPhone speaker, causing the audio failure.
• DND: The Do Not Disturb mode of the iPhone turns off the entire sound of the iPhone. The features are designed to make it silent. At times when you accidentally turn it on, the phone won't play any audio. It may be the reason for the error you are experiencing.
• External Connectivity: If you have connected your iPhone to an external Bluetooth device, it will be using that device for audio playback. Any error in the output device or obstacles between the device and your iPhone interrupts the sound and cause the audio error.
• Dusty Ports: The newer version of iPhones doesn't have a dedicated audio jack like the older models, but they do have a hybrid jack. If this jack gets clogged with dust or debris, it can interrupt the normal working of the iPhone audio system. The phone may detect an earphone and try to send audio output through it, but since nothing is connected, you won't get any playback.

• App Settings: Many times, when you play a video, you accidentally click a button or option that mutes the video. You don't realize this and think of it as an audio playback error.
• Microphone Error: The speaker of your iPhone is also vulnerable to damages over time. So, there's a chance that your iPhone may not have recorded the sound in the first place.
