Sound driver not working

[V3RT-ctrl]

Hi. I'm on arch. After following this guide https://gist.github.com/scaramangado/4e09031d782cbad8a4446ba101f43ef7 I get the error:

"[ 3.697780] gvusb2-snd 1-8.4:1.2: found audio at altsetting 1 endpoint 0 [ 3.698919] gvusb2-snd 1-8.4:1.2: cannot find the slot for index 0 (range 0-3), error: -16 [ 3.698924] gvusb2-snd: probe of 1-8.4:1.2 failed with error -16"
