Why isn’t sound playing from my TV when mirroring from my phone or tablet?
Often, the issue lies within the mirroring settings on your source device (phone or tablet) or the TV. Ensure that you’ve enabled the option to transmit audio along with the video during the mirroring process. This setting might be labeled as “Share System Audio,” “Transmit Audio,” or something similar, depending on your device’s operating system and mirroring protocol (e.g., AirPlay, Chromecast). Also, check the volume levels on both your source device and your TV to ensure neither is muted or set too low.
Another common cause is incompatibility between the mirroring technology used and the audio codec supported by your TV. Certain older TV models may not support newer audio codecs transmitted via wireless mirroring. If possible, try a different mirroring protocol or app if available, or consider using a wired connection like HDMI to ensure audio transmission. You can also check your TV’s manual for the supported audio codecs and compare them with what your source device is outputting.
What if I’m using an HDMI adapter and still have no sound?
When using an HDMI adapter, confirm that the adapter itself is designed to transmit both video and audio. Some inexpensive or older adapters might only support video signals. Ensure that the HDMI cable connecting the adapter to your TV is also functioning correctly; try swapping it with a known working cable to rule out a faulty connection.
Beyond the hardware, double-check the audio output settings on your source device. Many devices allow you to select the audio output source. Make sure that the HDMI output or the correct adapter name is selected as the audio output, rather than the internal speakers of your device. Restarting both your source device and your TV can also sometimes resolve temporary audio routing glitches.
How do I enable audio mirroring with AirPlay on my Apple device?
AirPlay should automatically transmit audio along with video when mirroring to an AirPlay-compatible TV or device. However, if you’re experiencing issues, first verify that both your Apple device and your TV are connected to the same Wi-Fi network. Also, make sure that AirPlay is enabled on your TV and that your Apple device is properly connected.
If the connection is established but there’s no sound, swipe down from the top-right corner of your iPhone or iPad to access the Control Center.

While there aren’t dedicated apps that solely enhance audio mirroring quality, using apps designed for general streaming or screen mirroring can sometimes indirectly improve the experience. For example, certain screen mirroring apps may offer options to adjust the audio quality or bitrate, potentially optimizing it for your specific TV and Wi-Fi network.
Furthermore, ensuring that the app you’re using to play the content (e.g., YouTube, Netflix) is up-to-date can also help. Newer versions of these apps often include bug fixes and performance improvements related to audio and video streaming. Consider experimenting with different mirroring apps or casting protocols to see which one provides the best audio quality for your setup.
Is it possible my TV’s sound settings are causing the issue?
Absolutely. The sound settings on your TV itself can play a significant role in whether or not you hear audio during mirroring. Check your TV’s audio output settings to ensure that the correct audio output source is selected. For example, if you have an external soundbar connected via HDMI ARC, the TV might be set to output audio through ARC instead of the internal speakers, even when mirroring.
Also, explore any sound modes or audio processing settings available on your TV. Features like surround sound simulation or audio leveling can sometimes interfere with the audio signal received during mirroring. Try disabling these features or experimenting with different sound modes to see if it resolves the issue. Ensure your TV’s firmware is up to date to rule out any software related sound output issues.
