Choosing Headset in Select Audio Device doesn't set input device

[bmaupin]

I'm suffering from a series of audio bugs so I'll try my best to explain.

Out of the box, the output device in GNOME setting is listed as Kaby Lake something or other. It works in 20.04 but the headset microphone isn't detected.

In 18.04 the audio didn't work at all, which required me to use this workaround in /etc/modprobe.d/alsa-base.conf from https://bugs.launchpad.net/ubuntu/+source/linux-oem-osp1/+bug/1864061:

options snd-hda-intel dmic_detect=0

The headset microphone still doesn't seem to be detected, but at least the output device has a more understandable name ("Headphones - Built-in Audio").

Yesterday I ran across this workaround in /etc/modprobe.d/alsa-base.conf from https://askubuntu.com/a/1233446/18665:

options snd-hda-intel model=alc233-eapd

Now I get a popup every time I plug in my headset, which allows me to choose whether or not I plugged in headphones or a headset. Great! Unfortunately, even if I explicitly choose Headset, the input device is not set to the microphone of my headset.

Thankfully the microphone of my headset is detected in the Gnome sound settings, so my workflow looks like this:

1. Plug in headset
2. When popup shows click Sound Settings
3. Manually set Input Device to Headset Microphone - Built-in Audio

The primary difference between headphones and a headset, so I would expect that if I click Headset, the Gnome Input Device would be set to my headset's microphone. I can't see any other reason why the system would ask me which I'd plugged in. Am I missing something?

In the meantime I'll try yet another workaround such as https://askubuntu.com/a/1229519/18665

Thanks!
