Audio Output from Monitor Buzzing Noise Problem!

Hey guys I need help with my Acer H257HU Monitor audio output making buzzing noise to external speakers. Whenever I play games like Borderlands 2 or an older game Burnout Paradise I hear a buzzing noise coming from my external computer speakers plugged into audio output from monitor. I made sure the green audio cable is plugged all the way in monitor's audio output and it still makes buzzing noise. Listen to it for yourself. It is really annoying noise. I am 100% sure there is nothing wrong with my Acer H257HU Monitor.

Here is the recorded audio clip of the buzzing noise I hear from monitor audio output to external computer speakers.

Already tried that

Already tried different speakers still heard buzzing noise Sad

Then not speakers.

Once in a while you get a client that says "it's not...."

Smile, work with them anyway.

Try the speakers to the PC next. You don't have to use the audio decoder in the monitor.

What happens if you unplug the external speakers and use the monitor speaker?

What happens if you plug your external speakers into the mobo?

Good question

I still hear buzzing noise though monitor built in speakers when external speakers are unplugged . When I plug external speakers into mobo I do not hear buzzing noise anymore.

Trying again

The easy fix is to plug the speakers into the mobo and be done with it.

Ok here's the thing

I use my monitor as a TV. That's why I have the external speakers and I don't use monitor built in speakers because they sound bad. So like I said I use my monitor as a TV to play wii u or watch tv.

Still need to test it direct to the PC.

Otherwise you won't know where the issue is.

Wow I feel stupid

Ok I really feel stupid now. All along the problem was DVI. DVI was causing buzzing noise all along. DVI is very obsolete why did I not think of using newer better HDMI or display port? Because I thought I could only use external speakers through DVI and I was wrong. I can use external speakers with HDMI by plugging in external speakers in audio output of monitor with headphones icon and I don't hear buzzing noise anymore using HDMI Happy

I don't think so.

While HDMI does have an edge I've not seen it fail like it did for you. Then again I rarely use other than AmazonBasics cables or the cables that come with my gear.

HDMI cables have a technical edge and this time, it paid off.
