No sound when playing Amazon Prime videos? How to fix

Have you been watching movies and noticed there is no sound on Amazon Prime despite having high-quality pictures? Audio or sound issues with Amazon Prime are common.

While there is no specific cause of this problem, there are several possible reasons behind it.

First, you may be using the wrong HDMI cable. HDMI cables can be used with older pieces of software or hardware without particular modification or adaptation.

However, additional capabilities can make them incompatible with some devices. As such, the cable will not transmit uncompressed digital audio and uncompressed video data from your digital TV, set-top-box, or computer monitor.

Second, the volume on your television may be low or muted. In that case, you need to check the audio setting and increase the volume.

Third, you have connected your Smart TV to an A/V receiver, but the receiver is off. To correct this, turn on the receiver.

The Amazon Prime video no sound problem may be annoying when streaming the latest movies. The following are other possible solutions for fixing it.
