loud hissing sound after update to 3.4.4.00

    I just connected for the first time my virus T12 Keyboard to my computer to update the firmware, everything seemed to have gone well until I turned it back on and I now have a constant hissing sound coming out of my outputs !
    I don't know what to do, I tried reversing to the older firmware but it does not seem to let me
    can someone help ?
    thanks !

    Hey MrAlex -
    Glad you sorted your issue, and bravo for good practice of saying what fixed it (not everyone bothers, what with the euphoria of climbing out of the hole!)
    Suzzy :)

    Hey ! Of course ! I think it's important the forum is always the first place I look since I really do not understand the manual...
    what is really missing is a section "Virus for Dummies"
    anywayTech Support have been great getting back at me and I will keep writing about what I find out as I go along ...
