User's Laptop – No sound

 Check audio settings on the laptop and ensure the volume is up (they may be different depending on the Operating System)

•  If using VGA connection, make sure the 3.5mm audio cable is plugged all the way into the headphone jack of the laptop.
  • If still no sound, unplug the 3.5mm audio cable and see if sound is coming from laptop speakers. If so, then there may be an issue with the AV system.  In this case, please submit a ticket or contact the HITS Service Desk to have a ticket assigned to the Audio Visual Support team. This is an older connection method and is no longer implemented.
• If using HDMI connection
  • Some spaces may not pass audio through the HDMI connection and will need to use the 3.5mm audio cable from the VGA connection. If this is the case, it should be outlined in the room instructions.
  •  If going directly into a TV via HDMI cable, make sure the TV is not muted and check if the sound settings of the laptop has selected the TV as it's output device.
•  If you are using Teams, Zoom, or any other web conferencing software that you are checking the software audio settings as well as the USB connection in the conference table. 
  
  

Microphones aren't working- no sound

Is the microphone on?

•  Lectern gooseneck microphones should always be on but may be muted or turned down. Check the Voice level and use the Up and Down arrows or Slider to increase the volume slowly until you hear yourself through the microphone. If muted see below.
•   Wireless microphones (handheld and lapel) are battery powered and have on/off switches. On some handhelds the switch may be towards the bottom of the microphone and hard to see.
• Some wireless microphones have rechargeable batteries and need to be set on the charging station after each use to charge, others have replaceable batteries and extras should be available in the room.

Is the microphone muted on the Crestron Touch Panel?

• Underneath the volume control for the microphone labeled Voice there is a mute button. It looks like a speaker with a line through it. Be sure this is not highlighted or flashing. This would indicate it is muted. If so, touch that button to unmute the microphone.

 If the microphone is on and unmuted, but still no sound, please submit a ticket or contact the HITS Service Desk to have a ticket assigned to the Audio Visual Support team.
