If there is no sound when you expect it or the
volume is too low or high, try the following solutions:
- Adjust the
projector's volume settings.
- Press the
A/V Mute button on the remote
control to resume video and audio if they were temporarily
stopped.
- Check your
computer or video source to make sure the volume is turned up and
the audio output is set for the correct source.
- Try disconnecting and reconnecting the audio
cable.
- Check the audio cable connections between the
projector and your video source.
- If you do
not hear sound from an HDMI source, set the connected device to PCM
output.
- Make sure
any connected audio cables are labeled "No Resistance."
- If you are
using the USB Display function, turn on the Output audio from the projector setting in
the Epson USB Display Settings program on your computer.
- 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.
- Make sure the A/V
Settings options are set up correctly in the Extended
menu.
- If you hear a hissing sound from your projector's
speakers when projecting from a computer running Windows 10 over a
network, you may need to adjust the Windows 10 sound
properties:
- Right-click the speaker icon in the Windows taskbar
and select Sounds.
- Click the Playback
tab, select the playback device, and click Properties.
- Click the Advanced
tab, set the sample rate and bit depth setting to 16 bit, 44100 Hz (CD Quality), click
Apply, and click OK.
Note: These
steps may vary depending on the Windows 10 version you are
using.
- 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.
