Vista - echo in sound

I have a strange echo when listening to youtube etc. It is worse if skype is logged in. have restored system, no joy. Cannot find my way back to the sound scheme setup that shows 'stone room' etc. Is it in 'personalise'. Many thanks for help

Forgot to say, the echo is in everything now, even the clicks when you go forward and back a page. Have quit skype and it is still there, cannot listen to anything.

Should I restore system or can anyone tell me where to find that 'stone room' sound scheme, because that is what it sounds like.

Many many thanks to you..it is driving me nutso

Hello luckylisa.
depending on what sound card you have you may or may not have a small icon down on the righthand side of your desktop, (not the small speaker, thats volume), scroll over them and see if you have a sound icon, right click on the icon and choose audio preset, there you will find the options you need, if it is not there, post your sound card type and we will go from there.

Hey stoneys-nutz, thank you for replying. There is only the volume icon. Where do I find sound card details?

Hi, take a look in control panel under sound or in device manager, again under sound, video. and game controllers, this should tell you what sound card you have.

I think you're referring to the Realtek HD Audio Manager found in the control panel.

Realtek High Def Audio?

Sorry, overlap in posts, yes it is realtek, but I still cannot find the 'stone room' thingie!

It looks like this

Aha, have found it without the images..it is on 'auditorium'. Should i change to 'generic'?
