No sound - new computer hooked up to HP VH240a

[Alpie]

New computer, hooked up the HP VH240a monitor.  Monitor works fine but there is no sound.  Hooked up through HDMI cable because there is no VGA on back of new computer, the old one was hooked up VGA and worked beautifully.  Do I need a VGA to HDMI adapter to get the monitor to work?

Hi:

I don't see from the product specs that the monitor has any speakers.

What has probably happened is if you are using PC speakers, when you connected the monitor via the HDMI cable, Windows changed the PC speaker default to the monitor default, and since the monitor has no speakers, you have no audio.

See if this works...go to the device manager, Hardware & Sound>Sound>Manage audio devices, and set the PC speakers as the default.

This monitor has built in speakers.  I've been using it for over 2 years.  Old computer apparently had lightning strike so bought a new computer.  It was hooked up to the old computer through a VGA cable but the new computer does not have anywhere for a VGA cable to hook to so hooked up using HDMI cable.  No sound!  Just tried a VGA to HDMI cable but then I don't even get a picture.

BTW - the computer sees the monitor as the source of sound.

[Alpie]

Yes it definitely has speakers - I've been using it for over 2 years.  Hooked up to new computer (old one fried by lightning) and there is no sound.  The computer recognizes the source of sound as the monitor but there is no sound.  Tried VGA to HDMI adapter but still no sound.  Does that mean that the speakers are fried?  There was no image when I hooked up with the adapter - went back to direct to HDMI and the picture came back.

Those VGA to HDMI adapters usually don't work because VGA is analog and HDMI is digital, so that is why you got no picture.

Also the sound wouldn't carry through a VGA to HDMI adapter.  It has to be HDMI to HDMI to get both video and audio.

Unfortunately I don't know what the problem could be.

Since your monitor has speakers the HDMI cable should have gotten the speakers to work if the monitor supports sound via HDMI.

How did the speakers work previously in the PC that was fried if it has a VGA cable connected to it?

Is there an audio cable with the light green audio jack that goes from the speakers to the back of the PC's light green audio output port?

You might want to try that if there is.

[Alpie]

Yes the green cable is plugged in.  Before it was just straight VGA - plus the green cable.  There is no sound when I test it now.  Beginning to wonder if it's the monitor's sound rather than any connection problem.  The monitor itself works fine I just can't get sound with the new computer.  Thinking I may have to buy a new monitor if I want to keep sound coming from there.

[Paul_Tikkanen]

Yes, it sounds like it, but it might just be what I wrote yesterday.

HDMI uses a different audio chip and when you plug a HDMI cable into a monitor, the PC switches from the onboard audio to the HDMI audio.

Take a look at this screenshot...you need to select the Realtek high definition audio device as the default audio device, not the HDMI connection.

[Alpie]

Nope - no sound out of there either.  It always was the monitor for the sound.  The computer recognized that with the HDMI cable plugged in but there is no sound.  When I changed it to what you just showed there was still no sound at all.  Thanks for your help.
