My laptop sound card is broken (mic input is fine tho) so I'm going to buy a FiiO E17, but I'd also like to get some surround sound when I play games. So I thought about this and came up with a solution I think, by the way the Mixamp is the old old one, the one that doesn't have USB sound input.
Sound: Laptop --> E17 --> Mixamp --> Headphone
Microphone: Laptop --> Mixamp --> Mic
Would this work or I'm just going to get problems? I'm open to other solutions
