Third Wheel

I used the same guide as most other people: https://www.reddit.com/r/rocksmith/comments/uvdxbh/guide_get_rocksmith_working_on_steam_deck/
It stopped working and I wiped the system for other reasons anyway. On reinstall, launching wouldn't even bring up a screen: it would just silently exit and the play button would light up green again.
I fixed this by going into the game properties and "signing up" for the Rocksmith 2014 "Beta". This reverts the October 2022 patch and that seems to be all there is to the fix.
The password to opt-in for the revert beta is "JustInCaseWeNeedIt" (ref: https://www.reddit.com/r/rocksmith/comments/xa49mq/important_update_coming_to_rocksmith_2014/).
Hope this helps anyone who's frustrated out there!
Proton/Wine doesn't seem to support multiple sound inputs so there is no way to even assign a second RS cable as an input device for multiplayer. I did not try with a microphone but that might work.
The last patch from Ubisoft in October 2022 (it is now March 2023) seems to have killed the ability to play on Linux. Luckily they provide a fallback mechanism to go to the previous version.
