Mic occasionally missing at boot - Razer Blade 15

Hi, I’m having an issue with my the built-in microphone in my laptop. (Razer Blade 15 Advanced / RZ09-03304E42). Most of the time, it works perfectly. However, every few boots, it is not detected and I don’t get any sound input at all.

Sound output always works fine; the input never stops working after a good boot, nor does it ever start working after a bad boot. If I plug in an external mic, that works fine. This is a dual boot system, and it works 100% of the time when booted into Windows, so I’m pretty sure it’s not any kind of hardware flakiness.

I’ve tried to take as much information as I can from both a good boot where the mic worked, and a bad one where it didn’t. (Link below.) I’m not really able to make anything of them, unfortunately.

I’d really appreciate any insight anyone could offer on this!

If it works with Windows, fastboot or hybrid shutdown might be the culprits.
