there might be an BIOS update you could try i don’t think it will fix 64 bit and even if it did 32bit apps probably take less memory for storing addresses.
on my AOD255E 64bit just works :tm:

apps like https://play.google.com/store/apps/details?id=com.parseus.codecinfo (https://apt.izzysoft.de/fdroid/index/apk/com.parseus.codecinfo) show whether or not you’ve got it, on my samsung galaxy note 20 ultra I’ve got software only :(

I’ve been using a phone without a headphone jack for 3 years now with galaxy buds, if i didn’t accidentally break the included usbc headset id be using that instead (even on pc) but i did so now i use the headphone jack on my wireless xbox controller on pc (connected to my pc via usb because my motherboard’s audio makes noises when the pc is basically doing anything and echoes my mic into my left ear on windows (not a toggle in software or anything but said problem goes away if i power cycle pc by psu and then boot into linux)) and on phone i get to deal with Bluetooth and if i did have a usbc headset again i wouldn’t be able to use it and charge the phone in a practical way (wireless charging is an option but my phone discharges faster than it changes wired (when connected to pc), wireless charging is even slower)
