The sound on my DVD player suddenly stopped working. What should I check first?
First, check if headphones are still plugged in. Next, check if the volume is at zero or muted. If it still doesn't work, restart the DVD player.
I'm playing a DVD via HDMI, but there's no sound.
Check the volume on your TV or projector. When connected via HDMI, the volume is adjusted on the connected device, not the DVD player. Also, ensure the DVD player's audio output setting is set to "HDMI."
Sound is only coming from one speaker.
If using an AV connection, this is likely due to a broken or poorly connected red or white cable. Reconnect the cables or try with different ones. If using built-in speakers, one of the speakers may be faulty.
I connected to a Bluetooth speaker, but there's no sound.
Check if pairing is complete. In the DVD player's Bluetooth settings, confirm that the speaker is "connected." If it's disconnected, re-pair it.
There is sound, but the volume is too low.
Maximize the DVD player's volume, then turn up the volume on the connected device (TV, speaker, etc.). If the built-in speaker volume limit is too low, we recommend connecting to an external speaker (Bluetooth or wired).
Summary
- First check: Volume, mute, and if headphones are still plugged in
- HDMI connection: Turn up volume on connected device, re-plug cable
- AV connection: Check red and white cable colors and connections
- Bluetooth: Often resolved by re-pairing
- Sound quality improvement: Recommended to connect to a Bluetooth or wired speaker
