I am so frustrated with this sound card and it's drivers. When I was using Vista it worked fine but now that I installed my Windows 7 upgrade and new Creative drivers I get a lot of drop out. I have installed, uninstalled and reinstalled several times and it never gets any better though that is what Creative suggested. I can't even find paid technical support from Creative.
Can anybody help me? I have a very nice set of Altec Lansing THX speakers that are not living up to their wonderful potential.
Thank you.
