I have a Asus Maximums VI Hero and would like to use that on board sound with my Logitech G930. But it uses usb and not 3.5mm. How would i convert the usb into 3.5mm. I cant find any adapters to due so.
The g930 is wireless, the USB connector to it is only for charging not data transfer. I don't believe you can do what you are after.
So how can I use my on board audio?
Plug conventional speakers into it, any particular reason you are trying to use the on board with g930? Doesn't make any sense to me but I might be missing the point.
