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):

So, a friend of mine wants to become a Twitch streamer, commenting over movies. I never used Twitch. He showed me some channels over there that made me confused. There are dozens of channels entirely dedicated to people providing minimal commentary to entire movies, animes, and TV shows which are displayed in full, although not on full screen. And they seem to be monetized, otherwise why would anyone stream 5 to 10 hours a day? They have ads.

I have a few questions.

First, how is that legal? Why aren't copyright holders taking these channels down? Do people really care about a streamer that mumbles a single uninteresting word every few minutes, or it's all just an excuse to watch movies for free? Why the same content that will get your video taken down on YouTube is apparently okay on Twitch?

DBFH is "the Internet's longest running charity marathon." For fifteen years now, they've fundraised on behalf of Child's Play Charity for children who live in hospitals and in shelters for victims of domestic violence.

The event runs continuously, 24h/day on their twitch channel for an expected period of roughly one week. During this time, unpaid volunteer entertainers play games, do contests and comedy bits, take challenges from chat for songs, dances, readings, etc. and call-ins from guests while simultaneously raffling and auctioning various game culture and pop culture related items donated by sponsors or made throughout the year by unpaid volunteer crafters.

Every year it's a really good time with a great community, so for those who weren't aware of the event I thought I'd mention it here. Last year alone the community managed to raise more than one million US dollars, and more than 7.1 million dollars throughout the life of the project so far, entirely for charity. Hope folks from here would like to join in and (if you can) donate (responsibly).
