Ubuntu 21.04 on the Framework Laptop

Framework Laptop 13 Linux
58

After digging around various stackexchange questions, I finally got my headset mic working on Ubuntu 21.04 kernel 5.12:

  1. I checked my codec version
    cat /proc/asound/card0/codec* | grep Codec
    This told me Realtek ALC295.

  2. Then I looked through the kernel documentation page here. In the ALC22x/23x/25x/269/27x/28x/29x section it lists dell-headset-multi for headsets that can also be used as mic-in.

  3. In /etc/modprobe.d/alsa-base.conf I added this line at the end:
    options snd-hda-intel model=dell-headset-multi

  4. Then restarted the laptop, plugged in my headset and now I see headset microphone and internal microphone as audio input device options in my sound settings.
