After enabling selective updates from proposed, I ran

I removed "options snd-hda-intel dmic_detect=0" from /etc/modprobe.d/alsa-base.conf and restarted.

I can see the onboard sound card and microphone in gnome's interface. I used alsa mixer to maxout all levels.
I was able to record sound and play it back using sound recorder
I was able to play music from spotify and youtube
I was unable to use the "test" feature of gnome settings : I can open the window, but neither the front right nor front left buttons in the test play any sound

Connecting my bluetooth headset correctly switched output automatically to the headset but didn't switch input to the headset. I was however able to manually set input to the headset. disconnecting and reconnecting the headset after manually selecting it didn't fix the autoselection of the microphone but that feels like an unrelated issue.
