When I turned on my laptop this morning I found I had weird distorbed 'far away' sound coming from my headphones. The laptops speakers work fine. I thougt maybe the old ones I had been using had probably died so I plugged a new pair in but nothing changed. The music from the background is louder and the voices in the songs sound like they are coming from a tunnel somewhere. I have maxed out the volume but it only distorts it more. I have looked at the drivers and IDT HD sound and everything looks and appears to be working fine; and everything worked fine last night. I have Windows 7, everything have been updated and I have no virus that I know of. I need to find a solution for this asap as I need the sound in the headphones for my business.
