Trying to fully ditch Windows for streaming. So close, but this audio issue is breaking me.

Okay, I’ve been grinding through the process of replacing Windows 10 in my Twitch streaming setup with Pop!_OS. I’ve got OBS dialed in, my old NVIDIA card is holding it together surprisingly well, and video performance is right where I need it.

But the audio. Is. Destroying. Me.

It’s this horrible crunchy, crushed mess when I stream from Linux. Same exact hardware, same OBS scene setup. On Windows 10 it’s crystal clear. I’m pulling audio from my mixer and theres no “Line In” I can see. Something in the Linux chain is mangling it.

Here’s a side-by-side if you want to hear the pain:

Pop!_OS (crushed audio): https://youtu.be/wQUVlufAQs8?si=RlGH8Z90dK0X9KhA

Windows 10 (clean audio): https://youtu.be/hbJzIHzg_ek?si=ThiZpbBgTk89qL2p

Sample rates seem to match, nothing obvious is clipping. I’m out of ideas and running on pure stubbornness at this point.

Would love to hear from anyone who’s made Linux work in a similar setup. Tips, gotchas, weird fixes. Whatever you've got. I'm so close to fully escaping Windows here. Grrr.

For reference, here’s how I got my Pop!_OS setup working so far (OBS + NVIDIA NVENC + GTX 960):
