I have just spent 2 days trying to fix my PC thinking it was my fault when all along it was a piece of software made availble on the manufaturers website to auto update soundcard drivers??? It screws up loads of settings and is impossible to remove. My system was perfect BEFORE the update but as it is 3 years old and it said auto update I thought I would go for it. How wrong I was. I have emailed them but dont hold out much hope. There are load of postings on thier forum so they are aware it cuses problems going way back.
