Asus LCD monitor headphone jack no sound?

by rave765 / April 6, 2011 4:44 AM PDT


My monitor is the ASUS VH236H. You can see it here..

I'm having a problem with getting audio using the headphone jack on this monitor with my headphones. The sound will continue to play through the monitors built-in speakers instead. No volume from headphones at all, even after turning the volume all the way up. I recently purchased this for use with a PS3 to use with HDMI and it works great but the sound is coming from the there anything I can do? I called ASUS tech support and I was just told to try another set of headphones -.-

Thank you,

Did you try another head phone?
by R. Proffitt Forum moderator / April 6, 2011 4:47 AM PDT

That's what we do at the shop to see if it's the jack not quite big enough to cause the switch.

If the display is new enough you consider taking it back to where you bought it.

We can also use a switch if all support fails to fix it.

Monitor came with this cable
by rave765 / April 6, 2011 4:56 AM PDT

The monitor came with a cable that looks like this except both ends are green... if I plug one end into the monitor's headphone jack and the other into my computer's speakers it'll play audio on my pc through the Monitor..after comparing the jack on that cable it seems to be the exact same thing as my headphones. What do you mean by a switch?

Thank you

That test shows the monitor is ok. If it wasn't the monitor speakers would have kept working.

While the plug looks the same it seems I would have to measure the diameter and length using something like to compare since eyeballing it may not be exact.

Sorry, but it's time to try another headset or BETTER IDEA!!! USE that cable with this adapter for your headset ->

Looks like you can solve it.

I will try the adapter.

Thank you, I will try the adapter. However the link you provided me has several items on the page, i'm not sure which one it is exactly? Can you link me directly to the one I need?

I did that on purpose.

Those 3.5MM female couplers are fungible. One should be as good as the next.

A perfect item to go get at a local store (BB, RadioShack, Fry's, etc.)

Adapter did not fix problem

Alright, just went to radioshack and bought a 3.5mm female coupler. The adapter works, but still no audio when using adapter from monitor to headphones or headphone directly in to monitor. I tested the adapter for the headphones straight to the pc speaker, works fine. I guess my only option is to try different headphones...

But it sounds like it changed the problem.

In in your first post you wrote:
"The sound will continue to play through the monitors built-in speakers instead."

Now you write there is no audio at all. I'm not there but this sounds like progress of a sort. That is, the headphones are clearly suspect.

Yes there is sound with monitor's speakers
by rave765 / April 6, 2011 10:49 AM PDT

There is sound when on the PS3 through the monitor's speakers. The problem is I don't get any sound to the headphones when plugging into the jack either directly in with the headphones or using the adapter. The sound on the monitor's speakers remains. I'm going to have to try another set of headphones..any decent recommendations?

The thing about headphones
by R. Proffitt Forum moderator / April 6, 2011 12:21 PM PDT

Is the entirely personal choice. Almost all have the 3.5mm jack so that's about the only criteria here.

Audio In port?
by nckchrst / September 26, 2012 4:43 PM PDT

I think your problem is that the port that you think is headphones is actually the 3.5mm audio in port to accompany the dvi or vga picture

Possible Solution
by robinhood1013 / October 29, 2012 11:08 AM PDT

Hello Dave, I have an Asus as well , I dont think its the same model number but on the back of your monitor there is a plug that matches the color of your cable. Green and says "AUX". When plugging a headphone, plug it into the other port located next to this green port , the color is black . Hook in the green cable into this black port and connect to your headphones it push sound through there.

hope it works,

Robin K

Sorry, this is coming about 4 months late, but absolutely this.

Thanks Robin for the deviously simple solution... honestly. The black input is hard to see.
