Make sure that the audio output setting of the HDMI output device (such as a Blu-ray Disc player) connected to the Wireless unit is set to 2ch LPCM. If it is set to a setting other than 2ch LPCM (such as Dolby Digital), no sound is produced.

Alternatively, restarting the projector may fix the issue.
