[lt.murda]

Ok heres the deal(using the onboard sound on my mobo).I come home froms lowes to play some css.I noticed that my sound was gone.So i unpluged my headset and pluged it back in.NOTHING.!So I pluged it half way in and its working..Now the sound is muffled(like the audio doesnt come through clear.I cant hear distant sounds or close ones for that matter clearly)I dont know whats going on.I played early today and all was fine.Help please

I went into the windows audio crap and I stuck my left audio slider for the left speaker all the way down on low and its working now.I cant tell a difference between the sound in the right and left.It must be driver related.Or my headphones are going out.CS:S is screwed but windows media player sounds perfect...im mad.
Well just got it workin.Sorry for the dumb ass post.
