Annoying persisting problem. Whenever I toggle my display’s input source, or my display goes to sleep and wakes up, the default audio is switched to HDMI/analog. I don’t want this. My preferred audio output is optical audio. I tried setting a HDMI audio blacklist in my modprobe.d folder, but it stopped working after a while. Might have been because of optimus-manager. I remember it working before that.
I’ve also tried editing my pulse config file, but that doesn’t seem to be working either.
