When I Bought My Computer My 5.1 Surround Sound Worked Just Fine.
Recently I Had To Reinstall Windows Vista Home Premium 32 Bit.
My Surround Sound No Longer Worked I Updated Drivers And Now My Speakers
Don't Work At All.
I Can Roll Back Drivers And They Work But Only In Stereo
I Have An EMachine T5224 With A Sigmatel Sound Card
