alsa-project/alsa-ucm-conf pull request #382 was edited from jhovold: Fix the Qualcomm sc8280xp and x1e80100 configurations which accidentally left the Speaker and Headphones mixer controls undefined so that the sound server falls back to software mixing. Also set the default volume levels in machine specific BootSequences so that the user can override the defaults.
