Sound & bluetooth not working on Ubuntu on MacBookPro14,1

I recently replaced Mac OS with Ubuntu 22.04.1 LTS on my laptop, and I can't get any sound to work through any of (a) the built-in speakers, (b) headphones connected via the 3.5mm headphone jack, or (c) bluetooth earbuds (bluetooth also doesn't work).

I've tried every solution I've found on askubuntu and ubuntuforums so, to be honest, I'm a bit stumped.

A (non-exhaustive) list of attempted solutions:

force re-loaded alsa
reinstalled alsa and pulse-audio, and force-reloaded alsa
started pulseaudio
re-created .config/pulse directory by renaming and rebooting old directory
unmuted all things in alsamixer
added "options snd-hda-intel dmic_detect=0" to a new line in alsa configuration file.
Installed Cirrus driver

Here's my machine information:

Apple Macbook Pro "14,1" (13-inch, 2017, two thunderbolt 3 ports)

Here's audio, system, and detailed machine info (result of "inxi -SMA"):

System: Host: connor-MacBookPro Kernel: 5.15.0-52-generic x86_64 bits: 64 Desktop: GNOME 42.5 Distro: Ubuntu 22.04.1 LTS (Jammy Jellyfish)

Machine:

Mobo: Apple model: Mac-B4831CEBD52A0C4C v: MacBookPro14,1 serial: UEFI: Apple v: 447.80.3.0.0 date: 12/12/2021

Audio:

Device-1: Intel Sunrise Point-LP HD Audio driver: snd_hda_intel

Device-2: Broadcom 720p FaceTime HD Camera driver: N/A

Sound Server-1: ALSA v: k5.15.0-52-generic running: yes

Sound Server-2: PipeWire v: 0.3.48 running: yes

I'm relatively new to Linux, so any and all guidance is appreciated! (I am also open to workaround solutions such as "get a USB-connected speaker, you dumb dumb")

Make sure you have the Cirrus driver installed for sound:

https://github.com/davidjo/snd_hda_macbookpro

ubuntu package install:

apt install wget make gcc linux-headers-generic

git clone https://github.com/davidjo/snd_hda_macbookpro.git
cd snd_hda_macbookpro/
#run the following command as root or with sudo
./install.cirrus.driver.sh
reboot

I used that process to download and install the Cirrus driver, and still no luck with sound. I edited the original post to include this attempted solution!

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
