Inbuilt microphone not detected on Thinkpad E14 Gen 6 (Pop OS)

I've just installed Pop OS as a dual boot on a new Thinkpad E14 Gen 6, running an AMD Ryzen 5 7535 CPU. I've got a problem though: the inbuilt laptop microphone is not being detected in the sound settings! The "Input" dropdown is greyed out, with no options to select anything. The laptop speakers work fine. One of the first things I tried was installing pavucontrol. This told me that the microphone was "unplugged". Running

--list-devices

gave me the output

**** List of CAPTURE Hardware Devices ****
card 1: Generic_1 [HD-Audio Generic], device 0: CX8070 Analog [CX8070 Analog]
  Subdevices: 1/1
  Subdevice #0: subdevice #0

Which I think implies that **some** part of Linux is detecting the microphone? Based off of my erratic googling, I've also tried blacklisting

to no effect, and briefly tried blacklisting

- which just made my speakers stop working. I reversed that! On top of this, I've ran this series of modprobe commands, to no visible effect:

131  sudo modprobe snd_sof_pci_intel_tgl
  132  sudo modprobe snd_soc_skl_hda_dsp
  133  sudo modprobe snd_soc_dmic

On the Windows boot, the microphone is detected and works fine! Some answers I've seen online have been telling me it's a kernel issue, but many of the answers are telling people to upgrade to 6.5 or 6.6. I'm currently on

.9.3-76060903-generic

. I'm not really sure what to do! Any help would be appreciated - or something to help me know where to look.
