[Bug] Tidbit's TRRS doesnt work

Describe the Bug

When I connect my snap to my tidbit via the right-most trrs port the tidbit powers up with static on the oled but otherwise doesnt work. Keypresses arent recorded. Both keyboards work fine when connected directly.

Here is the keymap/firmware I use on the snap.

https://git.qoto.org/freemo/qmk-firmware/-/tree/freemo/keyboards/nullbitsco/snap/rp2040/keymaps/freemo

Here it is for the tidbit: https://git.qoto.org/freemo/qmk-firmware/-/tree/freemo/keyboards/nullbitsco/tidbit/keymaps/freemo

As you can see the QMK app seems to have created a slightly different directory structure but I dont think that makes a difference.

Only other thing I tried so far was to turn on "SPLIT_KEYBOARD" in the rules for the tidbit. If I do that, however, it wont compile. I saw from other posts that this should "just work" so im not really sure what is going on here... Any ideas?
