…switched to component.
1. Do I need to enable a setting in the OSSC that will allow OBS to pick up the sound?
I’m not sure if it’s mentioned in the manual, but the OSSC ships with that TRS jack next to the HDMI port configured as an audio breakout for AV1. You need to hook the little switch next to the HDMI port with a paperclip or a butter knife or something and flip it to get that jack to function as audio input for AV2.
2. what settings do I need to change in the OSSC to get rid of these weird white lines.
There don’t appear to be any white lines in those last two screenshots, weird or otherwise.
