No Sound or Incorrect Volume

1. Raise the volume on both the source device and the glasses.
2. On the source device, choose XREAL 1 Pro+ as the audio output if that option is available.
3. Open 「Display and Sound」 > 「Audio Protocol」.
4. Switch between 「UAC」 and 「DP」, then test audio again. Use 「DP」 when there is no sound through an HDMI adapter or HDMI-based source path.
5. Disconnect and reconnect the cable after changing the source or adapter.

In 「UAC」 mode, the glasses can adjust volume normally even though the OSD does not show a numbered volume level.

If sound is distorted, test at a moderate volume with a direct connection and another known-good source. If the issue persists, note the source, adapter, audio protocol, and firmware version before contacting XREAL Support.
