by GitHub pull_request - opened 10 Nov '21

10 Nov '21

alsa-project/alsa-ucm-conf pull request #118 was opened from kholk: Almost all Trogdor Chromebooks are using RT5682 for headphones/headset on 3.5mm jack, internal microphone and headset microphone, and MAX98357A for the internal speakers (Lazor and Limozeen). This adds support for the sc7180-rt5682-max98357a-1mic sound card found on the aforementioned Chromebooks.
