Sound fading in and out

[astor]

A couple of days ago, the sound on my pc started to fade in and out. It does this on every program that emits sound. I've run virus scans, registry repair, computer cleanup, defrag, checked my cords (the issue occurs on headset at same time), updated drivers (says sound drivers are already up to date), etc.

I've browsed the web, but as yet haven't been able to find a solution, so I came here where I almost always get help.

As always, any and all assistance will be greatly appreciated.

did you install any programs right before this started happening?

do you have a sound card? (if Yes, then remove it and run audio from the mobo to try and isolate the issue)

--Edit--
to be safe, just post your PC's specs

No custom sound card. Just the mobo sound. I think it's a jack. Which means I'll need to get a card.
