Frequently Asked Questions

Why is my Fire TV audio out of sync?
Fire TV audio sync issues are usually caused by HDMI audio format conflicts, TV audio processing delays, or software glitches. The device may also struggle with certain audio codecs or have outdated firmware.

Yes, different HDMI ports may handle audio differently. Try connecting your Fire TV to another HDMI port on your TV, as some ports have better audio processing or less latency.
Should I use PCM or Dolby Digital for Fire TV audio?
PCM often provides better compatibility and less audio delay, while Dolby Digital offers surround sound. If you're experiencing sync issues, try PCM first, then test Dolby Digital if your sound system supports it.
