No sound - help please!

[Stephen Pollard]

Hi. I've installed Windows 7 on my VAIO. All seems fine but when I try to watch anything on YouTube, or listen to the radio, it's silent.
The volume indicators say it's playing at full volume, but it isn't.
Anyone have any ideas what I need to do please?
Thanks
Stephen

Let's just check the basics here: Is the speaker cable plugged in?
What sound card do you have? Can you please fill out you system specs?

 

[ickymay]

have a look in control panel / sounds to see if you have the correct device enabled ?

 

[Stephen Pollard]

I don't have a speaker. I listen through the speakers on my notebook pc. All was fine with VISTA!

 

[Jonathan_King]

Could you please fill out your system specs?

 

[Stephen Pollard]

Sorry, I am something of a computer idiot. I have a Sony VAIO notebook, which used to be Vista and is now Windows 7. I'm afraid I have no idea how I find out all the various technical things asked for. I just turn it on, find what I want to watch, and press Play! Only now there is no sound.

 

[Jonathan_King]

Go into Control Panel>Sound and post a screenshot. Instructions for posting a screenshot can be found here.

 

[Stephen Pollard]

here it is...hope it helps.

 

[Jonathan_King]

Now what happens is you click on the speakers and hit Properties? Please post a screenshot.

 

[Stephen Pollard]

Thanks for bearing with my ignorance!
Here are two more pics

Could you go to the driver tab and tell me what you see?

 

[Stephen Pollard]

These are from driver

 

[Jonathan_King]

Go into Device Manager and uninstall all drivers related to your sound card. Then reboot, and let Windows automatically install them.

Try this, set to DVD Quality. Usually clears up this type of problem.

 

[Stephen Pollard]

I'm afraid it hasn't made any difference.
I'm very grateful for the time you have spent on this.

 

[Jonathan_King]

Did you try Chev65's suggestion?

 

[Stephen Pollard]

Yup. Didn't work either.
I'm wondering if I should reinstall Windows 7 and see what happens? I won't lose anything as work is all backed up.

 

[Jonathan_King]

If you can, that might be a good idea. Let us know how it works out. Also, be sure to do a clean install, rather than an upgrade.

 

[Stephen Pollard]

will do

 

[Jonathan_King]

Did you do a clean install or upgrade from Vista?
