Hello Janine

Of course, if your particular monitor provide sound, (integrated) or the monitor has speakers, you can.
but if in the HUD menu, or visually you wont see any speakers, I fear not.

turned off , in the monitor. OSD setup.
cable fell off, (sound) or half plugged in.
sound turned own in PC or muted.
if you can't find out, why, try plugging in the monitor to another system and test it there, bingo, instant answers

Try checking your Cable connections to the Monitor to the Computer and from the Monitor to the wall outlet.The crackling sound maybe normal.Most Monitors make that sound.

Did you turn up the both (at the PC Audio control panel and at the Monitor control panel) volumes up?
Try using MP3 player or any audio sound sources feeding the monitor audio input to see what happen also.

Sound has to be connected to the monitor. Plug the audio cable from the monitor into the green audio jack on the computer at the back. Make sure the sound is configured for stereo and not 7 channel surround. Turn up the volume on the monitor(if there is a control) and turn up the volume on the computer.

u have to plug the sound connection on system properly

Please try to go to Control Panel > select Sound, Speech and Audio Devices > select Sound abd Audio Devices > then at Speaker Set-up select Monitor Stereo speakers. Best regards

when u turn off the system sound comes from motherboard not from monitor if there is showing any speakers in monitor

1. I turn on the monitor, I hear a 'cracklin' sound
Reply: In a CRT Monitor there is a component called EHT which generates High voltage which is connected to the anode of the CRT, If there is any leakage due to moisture can cause this crackiling sound, You need to clean this high tension wire or replace the EHT ( CAUTION : BE AWARE OF HIGH VOLTAGES )

2. The screen only shows a bright, thin line.
Reply: The vertical Drive section of the monitor is faulty.
