Question / Help Static Noise even with Mic/Speaker deactivated?

[confusingart]

Hey,

so I tried streaming but I noticed a static noise in the background. It doesn't matter if I activate/deactivate my mic/speakers.

I tried to adjust the volume of it but I can't. I don't even see a green line on the sound scale. Only hear it on my headset.

Connected to the PC with an optical cable, Trittion AX 720+


Additional question about Twitch: In order to be able to stream 720p I need to have ~ 70 viewers, right?
Additional question about Resolution: I have a 2560x1440 monitor but I can only downscale to 720 because 1080 doesn't appear.

Thanks in advance

Can you post your log? (Here's how)

You can stream at whatever resolution you want to Twitch. You don't have to have a certain number of viewers or be a partner.

As for the downscale, it's because there's not an evenly divisible way to downscale to 1080p from 1440. If you want to stream at 1080p, then I recommend setting the resolution manually.
