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.
- If you do
not hear sound from an HDMI source, set the connected device to PCM
output.
- 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 you
want to use a connected audio source when the projector is off, set
the Standby Mode option to
Communication
On.
- 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.
