Arctis Pro mic cutting out, only in Discord

I have an Arctis Pro I haven't used in quite a while because I use an Alias mic and headphones with a DAC these days. But my husband needs a new headset and I thought I could set him up with my old one for now. The problem is, the mic audio cuts out like crazy in Discord, but only Discord. If I do voice test in GG settings or on a Windows recording, it's perfectly fine. Any ideas?
