Asus/Bang Olufsen Audio dock compatibility with custom roms on TF300T

Does anyone know if the custom roms for the TF300T (for example KatKiss 6.01) support the official audio dock of asus Bang & Olufsen?

I would like to upgrade to a more recent version because the stock rom is getting sluggish, but I can only find support for the keyboard dock, not this audio dock.
