Hi,
If audio isn't playing through your USB headphones on a Samsung device, start by ensuring the headphones are properly connected and that the correct output is selected in the device's sound settings. Check for software updates, inspect the headphones and adapter for damage, and try a different set of headphones or adapter to isolate the issue. If the problem persists, consider checking developer options for a "disable USB audio routing" setting, which may need to be toggled off
