Classroom troubleshooting

• No sound from the computer, even though the touchpanel control volume is up.:

  • Check to make sure that the volume on the PC itself has not been muted or turned down by double (left) clicking on the speaker icon in the lower right portion of the PC screen and increase the volume.

  • Press the PC button on the touchpanel to ensure the audio from the PC has been selected in addition to the image.

  • If there is still no audio, click on the speaker icon on the PC again, then click the expand menu arrow. Playback device should be set to Realtek(R) Audio Speakers for most classrooms. In some instances, audio playback is through the AMX output device. If neither of these work, please contact the CTec helpline for assistance.

  • If the audio is coming directly from the PC's small internal speaker, it has most likely become unplugged. Please contact the CTec helpline immediately for a technician to reconnect it for you.
