A working picture does not prove the audio format and output route are correct. Check the player’s selected audio output, television mute and volume, active speakers and supported audio format. A receiver or soundbar introduces additional routing and compatibility settings that can affect sound independently of video.
Start with the obvious route
Confirm which device should produce sound: television speakers, receiver, soundbar or headphones. Bluetooth headphones can remain selected after use, and a television may disable its speakers when another output is active. Test a known working system sound or another app without immediately changing the subscription account.
Try a compatible audio mode
If the source uses an audio format the destination cannot decode, a supported PCM or stereo output can be a useful diagnostic comparison. Record the original setting before changing it. Passthrough sends an encoded signal onward and requires the receiving equipment to understand it; it is not automatically the best option.
Inspect the intermediate equipment
Check the receiver input and any ARC or eARC configuration if sound returns from the television. Video and audio can follow different routes, so draw the connections if necessary. Report whether all programmes are silent or only one track, and whether switching the audio language changes the result.
