I used the configs by default and tried all combinations for those 2 options
# Use ALSA-Card-Profile devices. They use UCM or
# the profile configuration to configure the device
# and mixer settings.
api.alsa.use-acp = false
# Use UCM instead of profile when available. Can be
# disabled to skip trying to use the UCM profile.
api.alsa.use-ucm = true
