• Check your computer or video source to make sure the volume is turned up and the audio output is set
for the correct source.
• Check the audio cable connections between the projector and your video source.
• Check the audio out cable connection between the projector and your external speakers.
• Make sure any connected audio cables are labeled "No Resistance."
• If you are using a Mac and you do not hear sound from an HDMI source, make sure your Mac
supports audio through the HDMI port. If not, you need to connect an audio cable.
• If the volume for the computer is set to the minimum while the projector's volume is set to maximum,
the sound level may be mixed. Turn up the computer's volume and decrease the projector's volume
(when using Epson iProjection [Windows/Mac]).
• HDMI audio is only supported using PCM. Make sure your audio source is set to the PCM setting.
• If you turn the projector on immediately after turning it off, the cooling fans may run at high speed
momentarily and cause an unexpected noise. This is normal.

• Make sure the Bluetooth Audio setting is turned on in the Settings menu. If you are using the
projector's speaker or headphones, turn this setting off.
• Select Search Bluetooth Device in the Settings menu when you pair a Bluetooth audio device for the
first time or change to another Bluetooth audio device.
• Make sure the Bluetooth audio device is paired to the projector and not to another device. See your
bluetooth device's guide for information about how to reset and disconnect from all bluetooth devices,
then try to pair to the projector.
• Make sure the Bluetooth audio device that is paired to the projector supports copyright protection
(SCMS-T) and A2DP.
• Check the volume level on the paired Bluetooth audio device.
• Make sure there are no obstacles between the Bluetooth audio device and the projector and that the
Bluetooth audio device is within the specified communication distance. Avoid using the projector near
wireless networks, microwave ovens, 2.4 GHz cordless phones, or other devices that use the 2.4 GHz
frequency band.
