I have a Scarlett 2i2 hooked up to Ubuntu Studio 22.04. I'm trying to get all sound to go through the headphone monitor, including Youtube videos. Currently, playback on Ardour and Audacity will go through the headphones, but videos continue to play on the laptop speakers.
I thought maybe I should set "USB device that should be master" in Studio Controls to USB1, the only option besides No USB Master, but then when starting Jack, it says "Failed to Start". If there are logs for Jack that would help, I wasn't sure where to find them.
I'm very new to all this audio software. I saw some information about using something called Carla Patchbay for routing the sound, but I was getting lost trying that.
