No its not Windows 10 before Whirly Fizzle spams the same solution that they have 20x over. That solution is not instantly the fix for everyone's problem and no I don't mean offense just stating it..[Saying this due to every post even remotely having the issue has that in it.] I've tried Firestorm/LL viewer and my voice is distorted beyond repair, I've tried everything in google search. It works fine in TS/Skype but not in SL. I am running windows 8.1 and no it wasn't a issue before.
