If there is no sound
from the
external speaker when you expect it or the volume is too low
or high, try the following solutions:
- Adjust the
projector's volume settings.
- Make sure external speakers are connected.
- Press the
A/V Mute button on the remote
control to resume video and audio if they were temporarily
stopped.
- 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 directly to
your speaker system.
- 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.
