Losing the audio feed on the Netflix streaming video or through-the-mail DVD services can be caused by an assortment of easy-to-fix issues, but can also be the result of more involved conditions. Netflix has been offering by-mail DVD services since the 1990s and introduced its streaming video service in 2007. Because Netflix services rely on several peripheral devices to work properly, such as DVD players, losing audio is usually related to one of these devices.
The Netflix streaming video service relies on a wired or wireless connection to the Internet and is viewable on a variety of electronics devices, including computers and video game consoles. The Microsoft Xbox 360, Sony PlayStation 3 and Nintendo Wii video game systems and several Internet-ready TVs are compatible with the Netflix streaming video service and rely on connections to a wireless router to work properly. Occasionally, the router, TV or video game console may not be able to keep up with the streaming content, causing the video to freeze or the audio to be lost. This often happens when the router is supporting more than one Internet connection at a time, and can be fixed by disconnecting one of the other devices from the wireless router.
If you have lost audio while watching a Netflix DVD or Blu-ray disc on a disc player, the problem likely lies with the device upon which the disc is being played. Often, Blu-ray and DVD players lose audio due to poor cable connections or disconnected wiring, which can come undone while moving the equipment from one room to another or while attaching new peripheral equipment to a TV. In most instances, these situations are fixed by checking and securing the wires and connective devices attached to the various electronic units.
Occasionally, Netflix DVDs and Blu-ray discs can get damaged while in the mail or from excessive viewing, which can lead to a loss of audio while viewing the disc. Netflix allows customers to report these issues directly to the company's customer service department or by reporting the issue via your online account. In either case, Netflix ships a replacement disc or the next movie in your queue immediately after you report the problem and does not count it against your disc-at-a-time limit.
Remote control settings are another common cause for losing audio while watching Netflix streaming video, DVDs or Blu-ray discs. Often, users inadvertently hit the "Mute" button on a remote control, making it seem as if the disc or streaming video has lost its audio. Sometimes, your electronics devices might simply need to be restarted to fix any glitches that might occur, such as losing audio.
