I had the same issue and it is still not perfect now but I was told by Anderton drums where I bought the software to download AS104 drivers instead of the native drivers for your sound card… You will have to go into settings after and muck about a bit getting it right but it took me about 15 minutes.
My biggest problem is I like to wear my Bose bluetooth headphones and it plays a lot quieter..
Thanks for the reply yes indeed you guessed right its the internal sound card all though it is not a generic card built into the motherboard its an Creative soundblaster 5.1 digital card with a optic output as well
