Sound problems on the Xbox Series S 512GB are often about where the console sends its audio, because it sends sound through the HDMI cable and also supports a headset on the controller and wireless audio options. If you have no sound, first check the TV volume and mute and the input, then open Settings, General, Volume and audio output and look at the HDMI audio setting: Stereo uncompressed works with every TV and is the safest, while Dolby Digital or Dolby Atmos for Home Theater need a TV or receiver that supports them, and a mismatch gives silence or crackle.
The checks in more detail
Change HDMI audio to Stereo uncompressed to test. If you use a soundbar or receiver, connect the console to it with the cable that supports the audio return channel or connect the console directly to the TV and use the TV's output, and check that the receiver is set to the right input. The Series S has no optical audio output, so a system that depended on optical needs HDMI through the TV or a different path. For a headset, the Series S has a 3.5 mm jack on the controller and supports Xbox wireless headsets.
If the headset works but game audio does not, check Chat mixer in Settings, Volume and audio output, which sets the balance between game and chat, and Headset format. Remove other connected audio devices, such as Bluetooth speakers paired to the TV, that could take the sound. If voices are quiet, enable Dialogue boost on the TV or receiver. If the sound cuts in and out, change the HDMI cable and try another port. In a game, check its own audio settings, since some games have separate mixes. Update the console and the controller firmware, restart the console and test with a second game or the home screen's sound.
If there is no sound on any output after the steps, contact Xbox support. If audio works on the home screen but not in one game, check the game's own audio output setting, since some titles have a separate speaker mode and a headphone mode, and a wrong choice silences the TV. Reset the game's audio options to default if the menu offers it, and install the game's latest patch. A game that sets itself to surround on a stereo TV is a common cause of silence and thin dialogue.
