I have attempted every solution I have found so far on remapping the channels for my headset including adding specific device profiles for it, none of worked so far. My current solution is patchwork that was supposed to split them by adding a device profile that knows how the device is to separate them(because it uses a dual channel layout, one stereo one mono iirc with one being chat and the other game), but it lacks the ability to handle/process those channels as a whole so I only can use one of the two channels at a time but since I at least have one channel that’s functional I have mostly given up on it. It’s just annoying cause that was the main reason for getting this headset, the ability to have a chat mixer to change voice call volume and game volume separately, it’s one of the few things that worked flawlessly on windows that I have been unable to get to work on the new system. I’m glad that you could find a solution that worked for you though, I have had no luck lol
that being said, if you know of a non-cli method of setting up pulseaudio custom profiles, I’m down to try that as well, maybe I just screwed my custom profiles up somewhere.
