Laptop to tv connection with hdmi produces no sound from tv

Hi everyone.
Please i urgently need your help.
I formated my windows 7 computer and reinstall windows 7.
Now when i connect the system to a television via hdmi cable, i get no audio from the tv. The audio still comes from the laptop.
When i go to manage audio device in the control panel, I see only the laptop speaker. There is no tv or external speaker (even though I have checked both the show disabled devices and show disconnected devices options.)
Checked my drivers, and windows tells me but the High definition audio hdmi and high definition audio controller are up to date.
( I have just one high definition audio controller driver under systems in the driver window. I am letting this know because i saw two in a picture posted online)
Have tries my laptop with three televisions (that work well with my friend’s laptop).
I really need urgent help. I will be very grateful for any help i can get. Thank you guys in advance.

The W7 reinstall

Would have a slew of drivers after the install from chipset to audio to other drivers.

This is usually rough on folk but I don't see the make and model so you'll have to detail every driver you installed for me to comment further.

Can give me your email so i can send your images of the drivers in my device manager. I am using an emachine d528 laptop by the way.

That's not how it's done.

Even with a shot of device manager I would not get it right. My method is to get the make and full model number then off to the maker's web page for bios, drivers and apps. It is hard on folk the first few times.

Hence folk fall for driver finders.

The maker and model number

Product: emachines d528
Model number: ZQ6
Marker: Acer

They don't make it easy.

Put D528 into the "Search by Product Model" box at

You'll start by checking the BIOS (last was 1.1)
Then the 4 drivers there.
There are user manuals but here's the really bad news.

This is a really OLD machine and emachines may have left you in a lurch. That's all the drivers I see listed and let's hope this clears it up.

If this fails, you want to see if the eRecovery media is still for sale.

Because HDMI sends audio and video

signals you have to make sure you have the correct playback device set. Right click on the speaker in your taskbar or goto sound in control panel. Make sure the playback tab is open and select the device that shows HDMI (sometimes it's the Graphics card if you have a discrete card).

Thanks for your help. But like i said the hdmi audio device does not show up in the playback list. That is the problem.
